Ok, so in your actionPerformed method, you put whatever code you need to do what you want when the button is pressed. Then you add the action listener to the button by writing the following:

myButton= new JButton ("Submit Grades");//inserting button
myButton.setBounds( 16, 45, 208, 218 );
myButton.addActionListener( new ButtonHandler() );
container.add(myButton);

That's all there is to it really...
