You don't. GridLayout is one of the layout managers that completely ignores all .setSize and .setPreferredSize method calls.
If you want to set the size of buttons in a GridLayout, you should add each button to a JPanel, and add the JPanels to the Container with a GridLayout. This way you can use, for example, a FlowLayout on the JPanel and use a button.setPreferredSize method call to try to keep the buttons a particular size.
