I've been wondering how to create a Blog Website using Dreamweaver.
I mean, with the Archive and Comment System.
The New post and the Old post thingy..
Or I've to use some special code?
I suggest you go with Wordpress, but you are asking a question so I'll answer that:
As stbuchok said, learn a programming language, because designing a blog is front-end, "designing" back-end is programming language.
Alternatively, take a look at a mini CMS such as Perch (grabaperch.com) which enables you to build some blog functionality into a standard site.
if you dont know html I suggest using a free template
