PIC, Voltage/Current and LCD

Hi!
i wonder if anyone can help me with finding suitable code for a PIC-controlled voltage/current-meter with a 16x2 or similar display..?

i'm not very good in coding, but i guess i can modify the code to fit my purposes, i am building a dual powersupply, hence the voltage/current display..

the voltage and current does not necessary have to be displayed at the same time, i can use a swith or encoder/knob to scroll..

i have got 16F84 to play with but it does not have to be this particular chip, any tips or idea are welcome!
