Wordpress seems to be really catching on and from the comments I have heard is a pretty easy to use program.
Since the original poster says he has Dreamweaver and Photoshop as long as he can figure out how to use them it is probably his best way to go.
I have never tried Wordpress but I will agree Dreamweaver can be a little tricky. Here is where I got the template that I based my site on. I think you will see some with grass right off the bat and they do have both Dreamweaver templates and Wordpress templates. http://www.flashtemplatesdesign.com/
I think if you do a search for "free Dreamweaver templates" you will find thousands to choose from and lots of gree ones.
