// TabPanels Class
package test.gui;


import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTabbedPane;


public class TabPanels extends JFrame{ 

	JFrame myFrame = null;
	// main to run and test this part of the program
/*	
public static void main(String [] args)  {  
    new TabPanels(); 
} 
*/
	public TabPanels() { 
	    JTabbedPane tp = new JTabbedPane(); 
	    add(tp); 
	 
	    tp.addTab("Tab1",new JPanel()); 
	    tp.addTab("Tab2", new JPanel()); 
	    tp.addTab("Tab3", new JPanel()); 
	 
	    setPreferredSize(new Dimension(1360,768));
	    //   myFrame.setPreferredSize(new Dimension(1360,768)); 
	    pack();
	    setVisible(true);
	} 
}


// layerOne class
package test.gui;

import javax.swing.*;


public class layerOne extends JPanel {

		
	public static void main(String [] args)  {  
	    new layerOne(); 
	} 
	
	private JButton btn1;
    	private JButton btn2;
    	private JButton btn3;
    	private JButton btn4;
    
	private JPanel myPanel;
	TabPanels tabs;
	
    public layerOne() {
        initComponents();
    }

   
    private void initComponents() {

    	tabs = new TabPanels (); // create new tab panels;
    	
        btn1 = new JButton();
           
        myPanel = new JPanel ();
        

        btn1.setText("Test");

  
        GroupLayout layout = new GroupLayout(myPanel);
        myPanel.setLayout(layout);
        layout.setHorizontalGroup(
                layout.createParallelGroup(GroupLayout.Alignment.LEADING)
                .addGroup(GroupLayout.Alignment.TRAILING, layout.createSequentialGroup()
                    .addContainerGap(236, Short.MAX_VALUE)
                    .addComponent(btn1)
                    .addGap(234, 234, 234))
            );
            layout.setVerticalGroup(
                layout.createParallelGroup(GroupLayout.Alignment.LEADING)
                .addGroup(layout.createSequentialGroup()
                    .addGap(137, 137, 137)
                    .addComponent(btn1)
                    .addContainerGap(214, Short.MAX_VALUE))
            );
        tabs.add(myPanel);
    }
    
       
}

Is that generated code? Try getting rid of that and writing the GUI layout yourself.

You are creating tabs, adding newly created JPanels to them which do don't have a variable to access them through, i.e. JPanel myPanel = new JPanel(); then you have a seperate class that extends JPanel() which is never used. Did you mean to do

  tp.addTab("Tab1",new layerOne());
  tp.addTab("Tab2", new layerOne());
  tp.addTab("Tab3", new layerOne());
