You can buy a cheap RC car and use the transmitter/ receiver pair to do what you want. The lowest-cost models do just that: control the motor off, forward or reverse.

Or, if RF is not a necessity, you can try an old TV remote control and receiver, but you need to add a micro to do the decoding and control the motor.
