Please dont waste my question if you cant do it. Thank you.

Above you should see a .java file: RecursionDemo. You are to create GUI for this program. It must allow user input and program output. Design your GUI to follow the functionality of the the original programs. In other words, familiarize yourself with how each of the programs work before attempting your GUI version. This time try to make your GUI user friendly. Tell the user what they must do and what outcome to expect.

Add comments to code please.
