I have supplied a pre-compiled HEX file, so you don’t have to worry about installing additional assemblers or having to compile things yourself. You will however need to get the program onto the chip. If you don’t know how to program a PIC, I would suggest you do some research on the JDM programmer, an even smaller PCB that allows you to program the chip through an RS232 port using freeware software such as PikLab if you’re a Linux user or ICProg if windows is your preferred PC OS. A quick warning: I'm told that the JDM doesn't work on Laptop Com-ports because they don't supply the required 12V, so keep this in mind if you build one. The total price to build a JDM programmer should be under 2€.
The Oscillator and Fuse settings in ICProg or PikLab should be: Oscillator = XT, WDT = Unchecked (off), PWRT = Checked (On) and CP = Unchecked (Off).
