Real Webmasters should know HTML/CSS very well, so there should be no need to use a WYSIWYG editor!!! Check out wikipedia Show me ONE site with DreamWeaver that is really GOOD coded!
Cubender is a Flash website builder that uses a drag and drop interface. To answer your question gabak, you can use any domain with a Cubender site. Of course all the while learning code..
350pages is a very good sitebuilder that I personally use. It has drag and drop and the ability to add your own domain to the system, and it's all simple WYSIWYG with a ton of additional popular 3rd party features for you to bolt on to the site. The basic version is free forever, but the upgraded version is damn good value for money
FancyCMS is also a handy handy product. you can edit your flash templates, flip book or galleries in WYSIWYG editor and upload anywhere. but its not free you will have to spend some bucks $15 or so
@OP i would spend the time to learn something like wordpress and joomla - in the long run your will find it more benifitially and like someone said here having a basic understanding of html, css and even php/mysql will really help you! hth
