Best thing is just to try it out.
Use one of the free hosting services like freehostia.com. or Heliohost.org. You can install a default Wordpress site with just a few clicks. From there you can play around with different themes, many are free, some are pay for. You can add plugins and generally get a pretty good idea of how it all works.
You'll need a url. You can get a free one from freenom.com.
If its all too much for you, or doesn't do what you want it to then hire someone to do stuff for you. It will have cost you nothing and you'll at least have some idea of how Wordpress works which you'll need to know regardless of which route it you take.
Even quicker is set up a site at Wordpress.com. Its easier but you're limited in what you can do. I don't think you can change themes for instance or add plugins.
