        {
            setLayout(new GridLayout(4,4));
            setBackground(Color.GREEN);
            this.setPreferredSize(new Dimension(500,100));



            JButton b1 = new JButton ("Button 1");

            JButton b3 = new JButton ("Button 3");

            add(b1);
            add(b2);
            add(b3);
            add(b4);
            add(b5);
            add(b6);
            add(b7);
            add(b8);
            add(b9);
            add(b10);
            add(b11);
            add(b12);

            add(b15);
            add(b16);

        }

    }



    public static void main(String[] args) 
    {
         JPanel primary = new JPanel();
         primary.setPreferredSize(new Dimension(500,500));



        JPanel jp1 = new JPanel();
        jp1.setPreferredSize(new Dimension(500,100));
        JTextField jt1 = new JTextField(8);
        jp1.add(jt1);


       GridPanel gp = new GridPanel();

       primary.add(jp1);
       primary.add(gp);

       JFrame jf = new JFrame();
       jf.setPreferredSize(new Dimension(500,500));
       jf.add(primary);
       jf.pack();
       jf.setVisible(true);

Try something like this :

public static void main(String[] args) 
{

   JPanel primary = new JPanel(new BorderLayout());
   primary.setOpaque(true);

   JTextField jt1 = new JTextField(8);
   jt1.setPreferredSize(new Dimension(0, 30));
   primary.add(jt1, BorderLayout.NORTH);


   GridPanel gp = new GridPanel();
   primary.add(gp, BorderLayout.CENTER);

   JFrame jf = new JFrame();
   jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   jf.setPreferredSize(new Dimension(400,200));
   jf.setContentPane(primary);
   jf.pack();
   jf.setVisible(true);

}

Look into using a BorderLayout for the JFrame, placing the panel with the text area you want in the Page_Start section and the GridPanel in the Center section.
