yes... you literally just need to power the pic(using decoupling capacitors as mentioned) have a resistor that puts the current in the proper range for your led connected to an output pin on your PIC... then the resistor connected to the led then connected to ground. If using batteries perhaps a 5 V regulator would be nice too.
