Setting up Multi Touch Virtual Joysticks to work on a PC

I’m looking to set up virtual joysticks but with the ability to use both joysticks at once. In my head it should be able to work, although a useless task on a pc with one mouse input, i am looking to then stream and view on a mobile device, which allows for the touch of both joysticks. So kind of harnessing PC power but being able to use it on a mobile device.

Anyone come across something like this? one joystick at a time works fine, but for the end user it is a bit restrictive.

Cheers
