Is that possible to control a craft using trackpad?

I use that game on macbook and I don't like keyboard control for Pitch/Yaw and other Sliders since it is not smooth.
So is that possible to do like this:
1. Consider touchpad as grid, where:

* Touchpad center: 0, 0
* Left bottom: -100,-100
* Left top: -100, 100
* Right top: 100, 100
* Right bottom: 100,-100

If a user presses a button (optional) and uses touchpad, a slider (e.g.) moves smoothly
