Help to use the K8096


is the first time I write, and I am a novice in electronics. I purchased a K8096 to control via PC, a stepper motor. I read that I can write my own program. I use the stepper motor to rotate a knob.
The card works well and I bought another K8096 to control another stepper motor with another function (to open a cap in front my telescope).
I would like to have a graphical interface with a virtual knob, instead of writing the steps and speed.
I’d like to ask if it is possible and how,todo it.I should use the Visual Basic? I have read that it is possible to connect some sensors on the K8096 . Can I have some link to who did it (just to understand different applications)

Thank You,
