Getting 4 columns for 3 more buttons.

I was able to get 4 rows with the buttoms but for some reason I can't get 4 columns for 3 more buttons.


final JLabel l1 = new JLabel();
        l1.setBorder(BorderFactory.createLineBorder(Color.yellow));

        p1.setBorder(BorderFactory.createLoweredBevelBorder());
        p4.setBorder(BorderFactory.createLoweredBevelBorder());
        p4.setBackground(Color.blue);
       
        p1.setLayout(new BorderLayout());
        add(p1, BorderLayout.EAST);
        p1.add(p2);
        p1.setLayout(new GridLayout(1,2));
        p1.add(p2);
        p1.add(p3, BorderLayout.CENTER);

        p2.setLayout(new GridLayout(1,1));
        p2.add(p4);

        p4.setLayout(new BorderLayout());
        add(p4, BorderLayout.CENTER);
        p4.setLayout(new GridLayout(3,3));
        p4.add(b1); p4.add(b2); p4.add(b3);
        p4.add(b4); p4.add(l1); p4.add(b5);
        p4.add(b6); p4.add(b7); p4.add(b8);
       
        p5.setLayout(new GridLayout(5,1));
        p5.add(new JLabel("Name 1\n"));
        p5.add(new JLabel("Name 2"));
        p5.add(new JLabel("Name 3"));
        p5.add(new JLabel("Name 4"));
        p5.add(new JLabel("Name 5"));
       
       
        p3.setLayout(new GridLayout(1,3));
        p3.add(new JPanel()); p3.add(p5);
        p3.add(new JPanel());
