in my experience, there is just as much coding to do with wordpress as there is with a static html site. because if you dont do your own coding then you'll be stuck with one of the generic templates that everybody uses.
if you're just planning on a blog that posts a few new things, and archives the old ones, then that probably wont be a problem. but eventually you'll want to start expanding the site to do other stuff, and that's when you need to learn how to code. you cant just rely on plugins, because a lot of them break when wordpress is updated.
but wordpress is good though. i'm still glad i used it.
