Also, this wonderful page too: http://compilers.iecc.com/crenshaw/ It exactly what you're looking for. No automated tool, library etc; In fact, you will need to have a automated tool: the Pascal compiler for compile your compiler. But I guess it is not a problem, right? :p the tutorial is really nice I’m at tutor6 right now and the guy really teaches step-by-step each little thing about we are going to working on. The toturial is unfinished but don’t worry, you can learn a lot with the contents he has provided so far. (sorry english, not my native language)

I would advise "Compiler Construction" from Niklaus Wirth book over that tutorial.

Of course, the best is to do both. :)
