JFrame frame = new JFrame();

ctsMenu.setPreferredSize(new Dimension(500,500));
for (int iRows = 0; iRows < 2 ; iRows++){
for (int iColumns = 0; iColumns < 2; iColumns++){
sGrid[iRows][iColumns] = new JButton ("("+iRows+","+iColumns+")");
ctsMenu.add(sGrid[iRows][iColumns]);
sGrid[iRows][iColumns].addActionListener(this);
panel.add(ctsMenu);

sGrid[0][0].setText("A");
sGrid[0][1].setText("B");
sGrid[1][0].setText("C");
sGrid[1][1].setText("D");
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);
