Online Office Football Pool Management

This year at the office, my partner and I are in charge of running the football pool.  In the past it's just been a big Excel spreadsheet that is printed out and passed around to all the players.  This time we want to set it up online so that everybody can access it from their own stations and be able to enter their picks and check results.

So I ask all of you: does anybody know of a good, but fairly simple office pool script, perhaps in PHP?  I don't have the time or the knowledge to design one myself, but I'm fairly confident in my ability to install a predesigned script.

I don't need anything fancy either, just something to allow players to pick a winner of each game.  Even if I have to input each team and the game schedule by hand.

Anybody know of anything like this?
