I have not tried this simply because we already have perltidy: 

perltidy -html -css=mystyle.css somefile.pl
Perltidy rocks. See also Perl::Tidy, which is the actual 'guts' of perltidy.

UPDATE:
Ooooops ... i glanced over "ranging from Perl to config files to Java, etc." Hmmmm, i do know that gvim has a menu command Syntax->Convert to HTML, but i do not know how to access this via command line. If you can indeed do such, a Cheap Solution® might be to fork and exec a another process. Coding only in Perl is another choice i can think of ... ;)

UPDATE x 2:
ndwg++ :)
