Grid within a grid

Question

Hi,
I am new to awt. I am trying to create a series of grids within a grid.
The first grid will have three rows and one column. Each of the rows will contain a grid of varying numbers of rows and columns.
Has anyone an example of how I would do something like this (no swing please, I haven't got to that part of Java yet!)
Cheers,
Didje

Hi,
Yes, that's where my problem has been. I've never done containers before, so I've been figuring how to nest them.
However, I have managed to cobbble the following code together, which basically works, but I can't figure out how to reduce the size of the top and bottom buttons to a similar size of the centre buttons.
import java.awt.*;
public class NestedPanel extends Frame {
public NestedPanel(String title) {
super(title);
setLayout(new GridLayout(3,0,0,40));
     addPanel1();
     addPanel2();
     addPanel3();
public void addPanel1() {
     Panel panel = new Panel();
     panel.setLayout(new GridLayout(0,3,15,30));
panel.setSize(10,10);
     panel.add(new Button("TButton X"));
     panel.add(new Button("TButton Y"));
     panel.add(new Button("TButton Z"));
     add(panel);
public void addPanel2() {
     Panel panel = new Panel();
     panel.setLayout(new GridLayout(4,5));
for(int i=1;i<=20;i++)
          panel.add(new Button("Button " + i));
     add(panel);
public void addPanel3() {
     Panel panel = new Panel();
     panel.setLayout(new GridLayout(0,4,15,30));
     panel.add(new Button("BButton X"));
     panel.add(new Button("BButton Y"));
     panel.add(new Button("BButton Z"));
     panel.add(new Button("BButton Q"));
     add(panel);
public static void main(String[] args) {
NestedPanel abc =
new NestedPanel("Nested Panel");
     abc.setSize(350, 550);
     abc.setVisible(true);     
}
