I would not use a PIC, but rather i would use something like the DS1621, which can act as a stand-alone thermostat. You will need a PIC to program the temperature set point and hysteresis though, and also you will need a PIC to display the temperature.

For the application you describes, i would use a mechanical thermostat. It is more reliable. You can make the circuit of course, but use it NOT alone. Add a secondary mechanical thermostat to avoid frozen surprises
