Help with Widget

i need some help making a custom countdown widget.... i just ordered my new '08 STI and it will be approx. 4 weeks before it arrives. i want to make a countdown timer for it.
here's is the logo or what not i would like on it:

if anyone knows how to make one, or could possibly make one for me i would appreciate it very much.

Why not just get the Countdown Plus widget from:

I have used it since I got my Mac and it works well.
