GUI paint printing

Question

I've got this hard coded line of painted ovals with a simple gui implementation after that.
However I cannot get the line of dots to show on the frame when i open it. The only way it shows on the screen is if i maximise then immediately minimise the screen. how do I get it to show on opening?
PuzzleSolver()
          super("Puzzle Solver");
          buildGUI();
          setSize(300, 300);
          setVisible(true);
          setDefaultCloseOperation(EXIT_ON_CLOSE);
     public void paint(Graphics g) {
          g.fillOval(70, 70, 05, 05); // Nodes
          g.fillOval(100, 70, 05, 05);
          g.fillOval(130, 70, 05, 05);
          g.fillOval(160, 70, 05, 05);
          g.fillOval(190, 70, 05, 05);
          g.fillOval(220, 70, 05, 05);
     private void buildGUI()
          /**This button closes the screen and returns the
          * user to the message board
          JButton c = new JButton("Cancel");
          c.addActionListener(
               new ActionListener()
               public void actionPerformed(ActionEvent e)
                    System.exit(0);
          /** The folowing code is a screen layout for the
          * Puzzle Solver screen */
          JPanel top = new JPanel();
          top.add(new Label("This is your Game Solution. Enjoy!"),
               BorderLayout.EAST);
          Container pane = getContentPane();
          pane.add(top, BorderLayout.NORTH);
          JPanel bottom = new JPanel();
          pane.add(bottom, BorderLayout.SOUTH);
          bottom.add(c,
          BorderLayout.EAST);
          pane.add(bottom, BorderLayout.SOUTH);
     }

Ah you see but if I make it a JPanel I can't access it via the main menu buttons. When it was a panel, (as my other page is) it doesn't open. That's why i made this one a frame.
Thanks a lot for all your help. no more worries I'll jus leave it not showing straight up
Thanks x
