Loosing & gaining focus of a window.

Question

In my GUI, I have created a window, that is having 2 buttons named "Enabled" & "Disabled".
MY requirement is: After execution of the window when I will click "Disable" button, the window should loose its focus and then clicking the " Enable" button the window should gain its focus.
Here I have written the code bellow for visibility of the window, but I haven't written code for the action to be performed by the 2 buttons.
If any of you have the idea about my requirement, please write me the updated code satisfying my requirement, sothat I'll proceed further.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class window extends JFrame
     public window()
          Container con=getContentPane();
          addWindowListener(new WindowAdapter(){
               public void windowClosing(WindowEvent e)
                    System.exit(0);
          JPanel p1=new JPanel();
          JPanel p2=new JPanel();
          JButton b1=new JButton("Enable");
          JButton b2=new JButton("Disable");
          p2.add(b1);
          p2.add(b2);
          con.add(p1,"Center");
          con.add(p2,"South");
          setSize(300,200);
          show();
     public static void main(String arg[])
          new window();
Regards.

Use a JDialog as the secondary window and make sure you specify the frame as the owner when you create the dialog.
