Dude, I'd like a new car that doesn't brake down all the time.

Are you looking for help with coding it or are you just looking for a sample project?

There's all kinds of sample code on this site and on the Internet.

Such as http://www.codeplex.com

may also some ideas on how to improve the application.

How would we know how to improve your application if you haven't written it yet?

Try writing some code and if you have problems come and ask more specific questions.
