Perl is a scripting language intended for stuff like string manipulation and stuff like that... It's ancesters are stuff like awk and sed.
It's probably not sophisticated enough of a language to need a IDE or anything like that.
The most that 95% people use to make perl scripts with is something like Vim with a perl plugin or Emacs, which are both standard Unix programmer-style text editors with obscure key combinations as a arcane sort of user interface, developed out of the days of text only terminals and acoustic coupled modems.
Notepad is pretty much all you'll ever need.
(not that I ever have done much perl, actually about zero. A little awk here and there and that's about it.)
