I would suggest to read src/README.md and the Devdocs ( http://docs.julialang.org/en/latest/devdocs/julia/) for an overview of the organization of the codebase.

Why is it implemented in that particular language? - C: because is the lowest-common-denominator for system implementations. - C++: because it is the most straight-forward way to interface with LLVM. - Scheme: because Julia is a Trojan Horse to finally make the world use Lisp. because it keeps the pesky peasants out. because it's a great compiler language and allowed fast implementation and iteration. There is some interest in moving the front end to pure Julia, and the parser has been ported already (JuliaParser.jl) -- that's about ~1/3 of the job. Porting the lowering and sorting out bootstrapping is a fair amount of effort and would likely need to be done by people who could be making more user-relevant improvements elsewhere. So far, doing so hasn't been a priority.
