Probably with C-h f generic-mode.

You could also base a mode of a simple one in emacs.
Or maybe this one:-

That's quite easy with Generic mode.

That is not so easy.  Syntax highlighting is done using regexp, this
makes it simple and fast, but not foolproof (except in the case of
something like lisp).  Syntax checking needs to be foolproof, so it
needs parsing.  You could write a simple parser in Emacs.

Or, you could make some regexp that find common mistakes and highlight
See cwarn.el in Emacs for an example of that.

They are.  Syntax highlight could be done by parsing in Emacs, but it
It is in some Emacs add-on packages.
