It depends on the amount of work you’re willing to put in as well as the complexity of your WordPress theme (assuming that you’re trying to match your bbPress theme to your WP theme?). Using CSS (which is what you use to style the site) is simple and enjoyable to me, but you may prefer to just get someone else to do it.

Everything is in plain English and the format is simple. Have a look at http://www.w3schools.com/css/
