Yes, but you still have to use the MAX232 transceiver on the PIC end, you cannot attach the PIC pins directly to a RS-232 Port. If you just want to receive data from the PC to PIC you only need to connect the one line and GND.
What kind of RF transmitter do you plan to use? You can attach RF tx to you PC port over a MAX232 cct as well. You can send commands to RF device from a PC terminal tool (like hyperterminal etc.)
