What's a good GUI to you?

Both are welcome, but I'm more interested in theory.
Johnny_B pretty much got it.

Big buttons, only modal dialogs. Stay away from open options and give people a list to select from. The average person recalls more from recognition than memory. Stay away from anything that would require recalling abstract information.

Provide feedback, again idiots will keep hitting things unless they get some kind of instant feedback.
