                try

                {

                UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");

                }catch(Exception e){}

        setLayout(new BorderLayout());

        setVisible(true);

        setDefaultCloseOperation(EXIT_ON_CLOSE);

        

        p=new JPanel();

        p.setLayout(new GridLayout(10,10));

        

                for(int i=1;i<=100;i++)

                {

                p.add(new JButton("Button "+i+"\n"));

                }

                

        add(p);

        

        }

        

        public static void main(String args[])
