    Default Grid bag layout inside grid bag layout

    As the subject suggests, I am attempting to put a grid bag layout inside another grid bag layout. It's turned out horribly wrong which you will see by running the code I have. What I want is to put the toppings panel in its own separate grid bag layout, but it is overlapping the rest of the GUI. I'm not really sure what the problem is.

    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import javax.swing.border.*;
     
    public class PizzaCalculator
    {
     
        public static void main(String[] args)
        {
        	JFrame frame = new PizzaFrame();
        	frame.setVisible(true);
        }
     
    }
     
    class PizzaFrame extends JFrame
    {
    	public PizzaFrame()
    	{
    		setTitle("Pizza Calculator");
    		setResizable(true);
    		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		JPanel panel = new PizzaPanel();
    		this.add(panel);
    		this.pack();
    		centerWindow(this);
    	}
     
    	private void centerWindow(Window w)
    	{
    		Toolkit tk = Toolkit.getDefaultToolkit();
    		Dimension d = tk.getScreenSize();
    		setLocation((d.width-w.getWidth())/2, (d.height-w.getHeight())/2);
