I did something similar in the distant past, that is I wrote subset of C compiler (functions, standard types, pointers) to imaginary assembler and then bytecode interpreter. It was awesome fun, but also I got so into it my - then - girlfriend started to question my commitment to the relationship. So be careful, this is really interesting thing to do :)
