Well chances are it's been done... But not by me 😛
I would suggest one that "looks like" a joystick and this article How Can I Monitor a Joystick, Keyboard, or Mouse in LabVIEW? would be a good place to start.
Also there's lots of LabVIEW stuff written for X-Box controllers too, that's another good place to start.
