It should take you at least a month of constant studying and practice just to get too intermediate level with C++.
And to be a proper coder for games like this you also have to understnd D3D and Flash and all kinds of other things that will take you many months to learn!
To make a good hack by yourself would take at the very least 6 months of education and training! People downplay how hard it is.. It is not something you can just learn in a day..
Its a LANGUAGE! Its like telling someone to learn to speak German in a day! Its just not possible...
