|laziness, impatience, and hubris|
There's a lot of theory about "bla grammars bla bla translators bla ... context-free context-dependent bla bla etc".
(here you can find a lot of grammars to many many languages).
This is not rocket science, it's engineering.
So I totally agree with you about not wanting to read 9999 books on the subject, you need to build something.
I'm not in any way a compiler/language expert but I do feel that you want to get down to business
so.. here's Parse::Yapp, here's an article , here's another article , here's some benchmarks and comparisons between different parser generators for Perl,
and another comparison , and another article. If you have further questions, I'm sure the monastery has lots of monks with knowledge of Parse::Yapp
so your questions will receive an answer.
Now go write a language and good luck !
