Not necessarily. It could produce byte-codes for a virtual machine, eg
the Java VM, or source code for another language, like C or Common
Lisp. Not to mention that if he is content with an interpreter for his
language, he doesn't need to write a compiler at all. I agree that it
is quite an ambitious project in either case though.
