Don't use the convience method, and instead construct the JOptionPane contents yourself.

Have a look at the javadoc.

To create and use an JOptionPane directly, the standard pattern is roughly as follows:
     JOptionPane pane = new JOptionPane(arguments);
     pane.set.Xxxx(...); // Configure
     JDialog dialog = pane.createDialog(parentComponent, title);
     dialog.show();


Here's the javadoc for one of the ctor's mentioning that you can pass buttons in the options array:

public JOptionPane(Object message,
                   int messageType,
                   int optionType,
                   Icon icon,
                   Object[] options)Creates an instance of JOptionPane to display a message with the specified message type, icon, and options. None of the options is initially selected.
The options objects should contain either instances of Components, (which are added directly) or Strings (which are wrapped in a JButton). If you provide Components, you must ensure that when the Component is clicked it messages setValue in the created JOptionPane.
