adding components to a JFrame

Why does the following code only display 1 button. Surely there should be 2 buttons.

JFrame myFrame = new JFrame();

myFrame.setSize(1000,1000);

myFrame.setLayout( new GridLayout() );

JButton button1 = new JButton("Fred");

myFrame.add(button1);

myFrame.add(button1);

myFrame.setVisible( true );
