I suggest using the same radio for all nodes.
Are the remotes to be battery powered? This is a key decision item.
An Anarduino mini-wireless can interface/bridge the wireless network to a PC via the mini-wireless' serial port.
You'll need to write the bridging software and the PC software using the PC's serial port.
Or the serial port on a RPi. And perhaps use Python on the RPi.
I've done the above for use with moving sensors.
