Without tying up lots of I/O pins or adding more chips, you are stuck
with PWM.  PWM can be done programmatically as well as in PWM hardware.
Depends on what else you have going on in the PIC.

If you are willing to add chips, you can use a serial interfaced DAC
with a driver after it.  This will use at least two I/O pins.
