panel.add(square[1][1]);

a.setContentPane(panel); // Use panel on Window

GridLayout layout = new GridLayout(8, 8,1,1);

panel.setLayout(layout);

a.setTitle("Wizard Chess"); // Change window title

a.setSize(300,300); // Change window size

a.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

a.setVisible(true); // Make it visible
