Looking for a Multi Tab Multi Post Widget. I am using studiopress news theme Genesis

I am looking for a widget to use on the front page of our school website. Something similar to like a post it pad with tabs across the top. So it would be layered. When you click on a specific tab it would show you the posts pertaining to that tab. I have been trying to find something for quite sometime but am new to this and haven't had any luck. Any ideas!
