WordPress Product Page

Hello,
A client asked me to create a website for her that would enable her edit the product page (she sells glass designs). I originally modified a WordPress theme and created the entire website from that. Would it be better to create most of the pages static, but make the product page from WordPress? Or should I try something like Joomla or Drupal for this project? I’m new to CMS and I would appreciate your input.

Thanks guys
