I guess that's what you want to do.

public class OuterFrame extends JFrame {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    OuterFrame outerFrame = new OuterFrame();
                    outerFrame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }
    public OuterFrame() {
        JFrame innerFrame = new JFrame();
        innerFrame.setVisible(true);
    }    
}

You have a MainFrame (OuterFrame), and you create it. But, you create a JFrame inside this MainFrame. That's not a beautiful thing to do, but it's certainly a way of opening a "JFrame inside the other". This will give you two "windows" on the screen. You could create countless JFrames inside the MainFrame.
