I use Wordpress and Smugmug separately with good success.
When you visit my main website; http://photosbytabor.com
, you can see the different tabs I've added to the navigation bar as well as one that says "gallery site", that tab, as well as the ones below go straight to my Smugmug page and it is an easy way for friends/family to find the galleries they are looking for as well as new clients to view examples of our work.
I too knew very little regarding html, however, I have learned a little at a time over the years and am getting pretty savvy. Also, I optimize ALL of my photos for Google, save them as key terms in PS. Export via the "Save for web" option reduce size, quality (slightly), upload into Wordpress, and SEO them extensively once they're there. It takes some dedication, but it is hard to do an image search in Google for anything related to what we do without at least one if not a dozen or so of my photos instantly popping up.
***edit to add: I use ePhoto, a theme created by a company called Elegant Themes. I also pay for hosting via Host Gator, whom I'm not thrilled with, however, I like them enough to at least recommend checking them out.***
I hope this helps!
