JAVA Roulette

I need a very simple roulette game in java. It needs to have gui. But very very simple. You need to have a table where you place your bets. like this:[login to view URL] And SPIN button. When you press SPIN random number is typed on the screen. No need for animation. It just pops up on screen, and it calculate your credit. Needs to be done in 24 hours. DON'T BE LATE !!! I'm paying half in advance, and half when it's done.
