Code!

Heh you would have to pretty heavy into wanting to code, knowing how to code or willing to learn to create your own simulator.

Then the real difficulty, beyond the relatively "simple" UI code and a single 3D graphics program is the physics code that actually makes things happen.

Now if you really did want to give it a go and know how to program, you could start with a premade physics engine like "Havok" to get you up and going. Save weeks or months of coding time assuming you understtod the real world phtysics enough already to even make it happen. Eventually though, to make something unique, something that behaved properly for various sale types etc, you would have to write the physics engine yourself (Or find someone else that knows a lot about it to help).
