What kind of C++ would I have to learn to make my own OS kernel? [closed]

So it is definitely possible. (Some of the comments above say it is impossible. Wrong.)

You may even want to steal his bootstrapping and build code, so that you can just dive right in and start implementing the "fun stuff".
