If your PIC has schmitt trigger inputs you can get away with just using a
0.1uF capacitor and a 100kOhm resistor (resistor to +5V, switch to ground,
capacitor to ground (across switch).

0.1uF*100kOhm=10ms, which is generally the "bounce" time of a typical
switch. I used it succesfully in a number of projects.
