Help with OnlineDegree.com Computer Science Lesson 15: Event Driven

[Mab81]

I'm stuck on Lesson 15 where you're supposed to modify an old game to give it a GUI. I have part of it working, but the instructor changes a bunch of sections of the code without showing how it all connects together after the changes. I've watched the video over and over and made all the changes, I just can't figure out how to call the different fuctions. Did anybody whose taken this get that game working with a GUI? I'm stumped.

I can try to look at your code too, if you need another eye.
