Dreamweaver is a production tool used to design and build websites. Wordpress and Drupal are content management systems. It is almost a different skillset in either case as Wordpress and Drupal can use themes designed by others and as such, minimal customisation or HTML/CSS/design knowledge are required to build a Wordpress or Drupal (or Joomla) website.
