This is not a computer program, but APC props has performance data for each of their propellers, listed by diameter/pitch, and power input, thrust, torque and so on for their props at different RPMs. Their charts even show how forward motion of their propellers on the model in flight affects the propeller loading. I've compared their tests, its pretty close.
