GridBagLayout

[MuslimCoder]

How do I code a gridBagLayout to arrange some components. Say for example a button and a text area?

import java.awt.*;
import javax.swing.*;

public class GridBagDemo {
    private JPanel getContent() {
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.insets = new Insets(5,5,5,5);
        gbc.weightx = 1.0;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        panel.add(getPanel1(), gbc);
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        panel.add(getPanel2(), gbc);
        gbc.gridwidth = 2;
        panel.add(getPanel3(), gbc);
        return panel;
    }

    private JPanel getPanel1() {
        JButton button = new JButton("button");
        JTextArea textArea = new JTextArea(4, 20);
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        gbc.insets.bottom = 10;
        panel.add(button, gbc);
        gbc.insets.bottom = 0;
        panel.add(textArea, gbc);
        return panel;
    }

    private JPanel getPanel2() {
        JButton button = new JButton("button");
        JTextArea textArea = new JTextArea(4, 20);
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        panel.add(textArea, gbc);
        gbc.anchor = GridBagConstraints.NORTH;
        gbc.insets.left = 10;
        panel.add(button, gbc);
        return panel;
    }

    private JPanel getPanel3() {
        JButton button = new JButton("button");
        JTextArea textArea = new JTextArea(4, 20);
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.weightx = 1.0;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        panel.add(textArea, gbc);
        gbc.insets = new Insets(5,5,5,5);
        gbc.fill = GridBagConstraints.NONE;
        panel.add(button, gbc);
        return panel;
    }

    public static void main(String[] args) {
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(new GridBagDemo().getContent());
        f.pack();
        f.setLocation(200,200);
        f.setVisible(true);
    }
}
