Hey Rach...it you wanted to make it really simple...why not do something with a foundation...then just cut out a pieces to make up a spiral...applique them on and then apply the hands to that? Just a thought off the top of my head. I'll think some more....
Here is a spiral quilt....you might use something similar to this look for the background for the hands.

This sounds like quite the undertaking, but should be lots of fun for you!
