Controlling stepper motor with respect to angle sensor with computer

Hello, I am an arduino newbie.
I just want to know if it is possible to control a stepper motor that is connected to an Arduino and an inclinometer sensor from a computer that clear user interface.
The stepper motor is used to drive a plate and the inclinometer reads the angle value.
I have attached a picture for a clearer understanding.

Also if you have an example for projects that use similar approach to this, please include the link.

Thank you.

Having a phone send control commands to an Arduino is possible. Google for it.
