Can trackbar values be sent from another device?

I have made a traffic light detection algorithm with OpenCV and Python. My script has some trackbars which I need to adjust and see the output to set a desired stage.

My script runs on my Raspberry Pi, is there any way I can send the trackbar values from another device on the same network on the RPi? For example, maybe make a phone app (I use Windows Phone BTW) which sends the trackbar data to the script and shows the output on my phone screen.
