Is it possible to use my laptop instead of a TV for playing Wii?

Maybe this is a silly question. The thing is, I got a Wii as a gift last Christmas, but I don’t own a TV. I’m broke, too, so I probably shouldn’t buy a TV right now.

I have a Dell Inspiron E1705 with XP Media Center edition. I have several ports on the back, but I think they may be output only. Is there some device I can get to take the a/v cable from the Wii and use USB for input?

Or something like this? Are there any cheap-ish, easy solutions?
