How hard would it be to make an application very similar to this one...

go to dvdprofiler.com (I'm not allowed posting links)

They already have one for mobile. Windows mobile. But I would love something like this for the pre.

You basically input the dvds you own into a database by either title or UPC, etc. You can then see all the cast, credits, info, how much it originally cost, etc. It's an amazing program and I have the free version on my desktop. Would love something for a portable device though.

Think this would be possible to do?
