I use Dreamweaver also and have written my site using XHTML.
As for what I think you were asking... there are many WYSIWYG type of editors out there today that make it pretty easy for most common people to start a website. If you really want to be a good website developer you need to know the code too. A good developer can use a tool like Dreamweaver and also code in NotePad.
I'm still learning but I try and learn as much coding as I can to help me become a better website developer.
