[SOLVED] couldn't find a way

[tOpach]

Firstly, I am sorry about that I asked same question in GUI and couldn't get a solution.
I try to write code for a telephone directory program. I wrote code for main fuctions(search-save-delete).here is code sample

import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;

public class Tel_Dir extends JFrame implements ActionListener {

    public static void main(String[] args) {
        new Tel_Dir();
    }


    JPanel mainpanel;
    CardLayout mainLayout;

    public Tel_Dir() {
        createGUI();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 300);
        setLocationRelativeTo(null);
        setAlwaysOnTop(false);
        setVisible(true);
    }

    private void createGUI() {
        mainLayout = new CardLayout();
        mainpanel = new JPanel();
        mainpanel.setLayout(mainLayout);
        mainpanel.add(new FirstPanel(null), "part1_layout");
        mainpanel.add(new SecondPanel(), "part2_layout");
        mainpanel.add(new ThirdPanel(), "part3_layout");

        JPanel panel = new JPanel();        
        panel.setLayout(new BorderLayout());
        panel.add(new SidePanel(this), BorderLayout.WEST);
        panel.add(mainpanel, BorderLayout.CENTER);

        getContentPane().add(panel);
    }

    public void actionPerformed(ActionEvent evn) {
        String cmd = evn.getActionCommand();
        if ("button1".equals(cmd)) {
            mainLayout.show(mainpanel, "part1_layout");
          
        } else if ("button2".equals(cmd)) {
            mainLayout.show(mainpanel, "part2_layout");
        } else if ("button3".equals(cmd)) {
            mainLayout.show(mainpanel, "part3_layout");
        }
    }
    public void actionPerformed2(ActionEvent e) {
        String cmd2 = e.getActionCommand();
        if ("button4".equals(cmd2)) {
           System.out.println("pushed");
        }
      
    }

    private class SidePanel extends JPanel {

        public SidePanel(ActionListener listener) {
            createGUI(listener);
        }

        private void createGUI(ActionListener listener) {

            setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
            add(Box.createVerticalStrut(4));

            JButton quickbutton = new JButton("QUİCK SEARCH         ");
            quickbutton.addActionListener(listener);
            quickbutton.setActionCommand("button1");
            add(quickbutton);
            add(Box.createVerticalStrut(8));

            JButton savedelbutton = new JButton("SAVE OR DELETE     ");
            savedelbutton.addActionListener(listener);
            savedelbutton.setActionCommand("button2");
            add(savedelbutton);
            add(Box.createVerticalStrut(8));

            JButton standardbutton = new JButton("STANDARD SEARCH");
            standardbutton.addActionListener(listener);
            standardbutton.setActionCommand("button3");
            add(standardbutton);
            add(Box.createVerticalStrut(8));

        }
    }

    private class FirstPanel extends JPanel  {
    	 

        public FirstPanel(ActionListener listener2) {
            createGUI(listener2);
          
        }

       

		private void createGUI(ActionListener listener2) {
            setLayout(null);
            JButton actionbutton1 = new JButton("action");
            JTextField tex = new JTextField(); 
            actionbutton1.addActionListener(listener2);
            actionbutton1.setActionCommand("button4");
            actionbutton1.setBounds(30, 30, 100, 30);
            add(actionbutton1);
            tex.setBounds(30, 70, 100, 30);
            add(tex);
        }
    }
  
    private class SecondPanel extends JPanel {

        public SecondPanel() {
            createGUI();
        }

        private void createGUI() {
            setLayout(new BorderLayout());
            add(new JLabel("Under Construction", JLabel.CENTER));
        }
    }

    private class ThirdPanel extends JPanel {

        public ThirdPanel() {
            createGUI();
        }

        private void createGUI() {
            setLayout(new BorderLayout());
            add(new JLabel("Under Construction", JLabel.CENTER));
        }
    }

}

}

I did not add code of functions(save-delete-search). Problem is about action button. It does not work. Also I need some Jtextfield on "FirstPanel" and I would like to give the coordiante for these Jtextfield. I want to take string value on texfield by using action button. Could you please tell me how to do these 3 things. I really need a solution. Thanks in advance.

Kind regards,

Salih Ozan IRBIK.
