I have the same trackpad, but I rarely use it because I didn't find it all that hand to point-and-click. I never considered to change the mouse button actions to my keyboard.
A tablet hold could be the fastest solution, you can find some
desktop mounts that can accommodate a 5.2" device. This could possibly fit the T650 Touchpad.
The angle to position it wouldn't be ideal. But at $17 you can give it a try and eventually mod it or use it as a base for a custom design.
If you could change the ball at the end of the arm to have a 90°-angle and if the arm is long enough you could mount it at the end of your desk and position it above your keyboard. It would have more possibilities for good positioning compared to the MAC solution you posted, which is fixed.
