Best code to modify into my own altcoin?

[4mherewego]

As an experiment I want to create my own crypto currency. I am not that tech savvy but I have some programming background, mostly Matlab and C. Which is the easiest open source crypto currency to modify? Ideal would be just to have a conf-file with seed, average block time, difficulty adjustments, name etc and just modify those lines of code with the rest done in the background. Any suggestions?
