Ohh, I'm going to have to disagree eclipse,
Although it's fine for basic sites and things such as templates can work well.
There are major problems with using dreamweaver, as with all wysiwigs it produces massive amounts of code compared to hand coding. Adding items to an existing app can be incredibly tough. Although compared to Visual Studio it's a compact and efficient application.
I've run into so many problems using Dreamweaver which would never have happened in a structured hand coded site. Try using Dreamweaver in a team and you'll certainly find it's limitations quickly - no source control, impossible unusable functions and it forces you to use unrealistic file structures.
I'm not saying there is anything wrong with using Dreamweaver and it certainly depends on what your producing but it's certainly not ideal.
As a web designer the chances are as you go through your professional life you'll be doing one of these things - start to learn your syntax as your designing and it will stand you in good stead later.
