I've created just what you are looking for using a common web-based survey tool as a front end. You can see this at the link below:

This front end has been integrated with back end software I've also created named the Handicapping Contest Manager's Electronic Workbench. (see the attached Main Menu).
With the front end and the back end tightly integrated, I can publish the contest winners very soon after a contest ends.
Feel free to make use of this as I am looking for field testers. No cost to you.
