So in essence what you've done is to give us your entire assignment without asking a question and without showing any evidence of effort on your part, and I'm afraid that in this situation there's not much that we can do for you other than to direct you to a tutorial or two.
I suggest that you post your best solution that you've created so far, and ask as specific questions as possible, and we'll be much better able to help. If you really have no idea how to begin here, then please have a look here: Starting Writing a Program. It's a wellwritten article that can help.
Much luck
