Student Software Idea

Being that I myself am a student at college I had an idea for a product that a lot of users might like. As I said before I am a college student and as such I use PortableApps for managing my course work and studies. It would really be cool if someone wrote a flash-card program. Something that allowed students to create personalized flash cards for their various classes and then allow the student to be able to keep them sorted and go through them randomly or in a set order. If anyone knows of a program that already does this or would be willing to give it a go I'd love to know about it.

Thanks Everyone
