Well, I'm having a terrible time with grid(). I do have the 6 buttons 
in the same row, but they're a real mess. Someone please run this and 
tell me how to get them looking better.

When I use pack(), the buttons are nicely centered, but lined up 
vertically, one above the other. Maybe I can live with that. But I'd 
still like to learn how to use grid() well.
