Who even needs a kernel? First start learning to program on the bare metal, like us oldsters used to do. The Arduino environment is wonderful for this. Dirt cheap, easy to get started by copy/paste code, and the environment is full C++. I have thousands of lines of code running on Arduinos and none of it took skills that a 12 year old couldn't master.
