Hardware is easy, you would need a tx module. Perhaps something like this:

The module needs 5V and has an UART interface. Also note the tx module is a transmitter, but also a receiver - It receives telemetry data like drone position, altitude.
I don't know if there is a software for PC available that can control the drone directly, like in a game. Check this page for software that is used to plan gps waypoints for drones:
