Kind of difficult/kinda not difficult?

I was wondering if there was a way to achieve what I want to do, and what I have to do to achieve it.

I have this setup right now: http://www.usd226.org/db

I want to make it to where when someone votes, a popup comes up, saying "Thanks for your vote!" and in the background of the actual poll, I want it to display something rather then the results. Is this possible? Is there any certain files I need to edit, and if so, what files? All help would be greatly appreciated.
