edit:^^Actually, I really like Weebly. I used them for a long time to design and maintain a site for a farm I worked for, and at least at the time they were extremely easy to use and you could totally customize the site. I started with a really basic free template and made it look almost completely different...about the only elements that remained were the navigation bar and the background color, which were why I picked that one. LOL Unfortunately that site is long gone as the farm went out of business, or I'd link it...but it was quite nice, if I do say so myself.
That was my first attempt at web design too. I actually think Weebly is (or at least was) easier to customize than Wordpress. We also hosted pictures of all our horses for sale and our stallions (about 60 photos at a time, generally), plus our facility. In addition, we had a regularly-updated news feed (basically a blog) that we also posted pictures of recent events on. I'm not sure how much we wound up paying for it since I wasn't the one paying the bills on it, just doing the work, but I don't think it was much at all for what we were able to do with it.
I have experience with both. I personally prefer Dreamweaver, but I think it kind of depends on your situation--what kind of site you want, how much you want to spend and what kind of experience you have with web design programs.
I think Dreamweaver is much harder to learn the basics of. Wordpress is really easy to get started with and design a nice basic website with right off the bat, and there are easy tutorials for like everything. When I learned Dreamweaver I had to steal my dad's big how-to book on it and basically go through the whole thing. With Wordpress, you can just find a theme that has most of the elements you want (and especially if you're willing to pay for one, there are some really nice ones), and then customize it. You can also easily look up the specific tutorials you want. Basically, all the legwork is done for you, but the sites are really extremely customizable.
Wordpress is also going to be a lot cheaper than Dreamweaver. Like, I'm not sure you could make a Wordpress site cost as much as buying Dreamweaver if you tried, even if you go all out with bells and whistles. Last I saw, it was retailing for around $400. I have it because I do some web design work with my dad (he delegates the boring stuff to me LOL) and so I get included in his copy, since he has a business license for it.
Wordpress is also really great for photo galleries, from what I understand. I know some of my favorite photo blogs are done through Wordpress. I also think it is really easy if a blog-type feature is going to be on your site.
If you wanted to design a site totally from scratch (as opposed to customizing an existing template), then I'd probably lean towards Dreamweaver just because from what I've looked at, learning it is a lot easier. However, I'm also biased since I've been familiar with Dreamweaver for years and just done a few easy blogs and such on Wordpress, so I'm not sure you should listen to me there.
I'm sure others will disagree, but that's been my experience of the two.
