If you want to go the professional way, then you should go for Dreamweaver, this is part of Adobes (adobe.com) CS3 suite and it's worth getting and is probably one of the most important tools for professional web design these days, however you don't seem like you know a lot about web design so I would suggest you start with a simpler program, you can search for WYSIWYG editors on Google, I would suggest you start off with FrontPage then as you start to learn more advanced HTML and maybe other codes you can move on to the bigger programs like DreamWeaver.
