If you want to run native homebrew, you're going to need to learn C or C++. Nether of those languages are really suitable for beginners -- they're not languages an average person can learn in a week.
You can use script interpreters like luaplayerplus (write in Lua) or 3ds.js (write in Javascript) to run higher level code but you wouldn't have nearly as much control over the console as you would if you wrote it natively.
