USB

I am assuming that you PIC does not have an embedded USB.

You will have to use (you can try ebay) a SERIAL <--> USB converter. Connect SERIAL side to the PIC and the USB side to the PC (needs drivers if using Windows).

I've used this solution a lot of times.

Best regards.

The solution given by Fernando Machado, is very much feasible. 

Your PIC Micocontroller and your computer/laptop can be made to communicate with each other using the USART communication protocal. 

I have already made a tutorial (link below) which explains how this could be done
