I used to help nonprofits and small businesses build websites. Process always went like 1. buy domain, 2. buy a shared hosting provider that one-click-installs Wordpress, 3. use a theme to begin editing the website. Often, I would also use the email included with that hosting provider for the firm.

ALL of that goes through cpanel, for every shared hosting provider I can ever remember using. Even if the stuff happening on those servers didn't use perl, cpanel itself -- the admin of everything provided for that domain by the hosting provider -- it's a huge surface area.
