You do not need to have a "Quit" button in your calculator. When used inside of a web browser an Applet can't really quit. Since your applet consumes no resources when it is not visible, there is really nothing to do in the way of "quitting".
Your calculator should use type double for all values to provide for maximum flexibility.
As an extra feature you might want to read ahead in section 9.5 about layout managers. You can use the GridLayout class to arrange the buttons of your calculator in a nice grid. This is strictly optional.
When you submit this program be sure and submit not only your .java file but also your html file that includes an applet tag for your applet.
