Possibly not. At the moment, the Content Management System's such as Joomla and Drupal seem to be the way to go. They drag and drop too, but the only draw back there is that you do need a host/server that is CMS friendly and has one click install for Joomla, Drupal or WordPress. They are database driven, so you can do quite a bit more with password protection and member only pages if that is the route that you want to go.
A of people that I know that have commercial ventures, have recently transferred their websites to WordPress. A lot of people have migrated their sites to WordPress, for ease of use and shopping cart facilities, as well as member only pages.
I am in the process of transferring my sites over to Joomla and have just signed up for some new hosting with http://www.siteground.com, which specialise in Joomla hosting. Joomla 3 is good and easy to use - take a look here at http://joomla.org.
There are other hosts around that are also Joomla and WordPress friendly - HostExcellence etc. http://www.hostexcellence.com.
There are lots of alternatives out there if you look for them - DreamWeaver is not your only option.
