Pixelogist talk about Developing C-41 Color Negative Film explain how simply it can be done at home.
Alright, developing C-41 is pretty similar to the black and white process. The equipment is the same, so just check out my previous post on developing equipment to know what you will need. All of it applies – developing tank, beakers, thermometer, timer – all that. The chemistry is different but again, there’s developer, there’s fixer, and there’s something afterwards. The process, while different in order and times, is also very similar to the black and white process, so if you’ve worked black and white before, you should have no trouble with C-41.
My take: it might be harder to obtain the chemicals than to actually do it.
