Right now, I've just got the interface of the calculator. It's not too great and that's one thing I would like help with, any improvements will do. Also, the biggest thing I need help with, is the textfield. If you look at other calculators, you see they go right to left, instead of left to right. How can I do this? Another thing, I tried the setMaximizable(false) method, and it didn't work.

Hope I'm not asking to much.
