Does anyone know of a Jeopady style program that makes it really easy to load in new content / quesitons?

Of course there is a Jeopady video game but it's questions are fixed and not related to school standards, and there are power point presentations out there that let you actually use your own content, but to change the content you have to actually go to every screen and position and size everything yourself. This should be unnessary. There is no reason that the questions and answers could not be set up on a single screen that looked like an excel spread sheet and then have the program automatically distribute this content to the appropriate slides, saving a ton of time. I could write this myself in VBA, but guess what? I don't have the time. :-(

Is anyone aware of something like this that already exists? 

Would anyone be interested in buying such a program?  I will probably want to use it as a free give away with one of my pens, but if it could make its own money then I could make it more of a priority.

Thanks.
