How would i control the rotation of a circle by touch?

Could any of the GameSalad maths guru's out there suggest a way how to rotate a circle by touch.
So Im thinking along the lines of like a steering wheel.... where i touch the circle around the edge, and as i move my finger in an arc the wheel rotates with it.
Im thinking I'd have to work out the angle of the touch from the centre of the wheel and compare it to the next touch, and then somehow the difference of position would dictate which way, and by how much i'd rotate the circle.... or something like that....?
Anyone willing to throw together an example of how i might do that....
