JFrame calling a JFrame....

Question

Hello,
I was trying to create a JFrame which has a BorderLayout() and there is a button set at the SOUTH of the layout of this JFrame........
Now when I click on this button..... this event would create another JFrame which also has a BorderLayout() and a button located at its SOUTH......
Now the problem is that when I click on the button of the first JFrame, it creates another JFrame as expected but it does not create the button at the SOUTH of this new JFrame...... How do I overcome this problem......
The code is given below..........
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TT extends JFrame implements ActionListener
     JButton but;
     public TT()
          setLayout(new BorderLayout());
          but=new JButton();                    
          but.addActionListener(this);
          add(but,BorderLayout.SOUTH);
     public void actionPerformed(ActionEvent ae)
          JFrame jj=new JFrame();          
          JButton jb=new JButton();
          jj.setLayout(new BorderLayout());
          jj.setSize(100,100);
          jj.setLocation(300,300);
          jj.setVisible(true);
          add(jb,BorderLayout.SOUTH);
     public static void main(String args[])
          TT obj=new TT();
          obj.setSize(400,400);
          obj.setLocation(200,200);
          obj.setVisible(true);
}It would be highly appreciated if anybody who knows the answer would take the PAIN of answering this question....... Thank you in advance.......

Hai,
Execute this modified code. It's executing perfectly. U better assign some text to the button.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TT extends JFrame implements ActionListener
     JButton but;
     public TT()
          getContentPane().setLayout(new BorderLayout());
          but=new JButton();                    
          but.addActionListener(this);
          getContentPane().add(but,BorderLayout.SOUTH);
     public void actionPerformed(ActionEvent ae)
          JFrame jj=new JFrame();          
          JButton jb=new JButton();
          jj.getContentPane().setLayout(new BorderLayout());
          jj.setSize(100,100);
          jj.setLocation(300,300);
          jj.setVisible(true);
          jj.getContentPane().add(jb,BorderLayout.SOUTH);
     public static void main(String args[])
          TT obj=new TT();
          obj.setSize(400,400);
          obj.setLocation(200,200);
          obj.setVisible(true);
