Ok then. Do you have any specific questions? For a start you can get MPLAB for free and the microchip assembler, or some other assembler for 8 bit PICs. Then just look at some example assembly code about controlling the ports, and about reading ADCs. Get the datasheet for the chip by searching its number and "datasheet", read the intro, features, and the sections on the ADC and ports. Once you've done this stuff you'll have a good start and should you have any problems, you can ask more specific questions.
