Well, for one, you will have to implement the memory/system model for the language. It may or may not have access to the host language's "printf" function.
Initially of course, a shortcut way is to leverage as much of the host language's features as possible, then eventually, as you move further into the bootstrap process, you will want to remove reliance on the host language.
