migrating from iWeb?

I’ve built several sites using iWeb, but Apple’s move to iCloud will kill blog comments, so I’m looking elsewhere and have a question about WordPress:

Can you build a site with multiple blogs? Specifically:

On http://www.mouzon.com, I have a blog where I archive news, a bunch of blogs where I sell our house plans (one blog for each plan type,) two blogs for our image collections, a blog that is our book store, three blogs that describe our services, and a conventional blog where I talk about the things that might be interesting to those that follow our work.

I do similar things on originalgreen.org, newurbanguild.com, and guildfoundation.org, taking blogs to places they don’t normally go.

I did all this in iWeb, knowing almost nothing about html. Is it possible to replicate these sites with WordPress without dedicating months of my life to learning html? Or is it even possible at all?
