How difficult would it be to create this as a template?

Here’s the link: https://www.freelayouts.com/templates/Health-Care-Website-Template-008

I’m thinking its just 3 columns, the right column is where the widgets would go (pages, posts, adsense)
The boxes I’m assuming are widgets that you can put into the document, like the way I use the adsense manager plug in to put adsense widgets within my posts.
The top is where the pages would go and the rest is just css, right? Of course I’m terrible at css.

Is there a WordPress Template/Layouts for Dummies type book?
Or even better, a basic 3 column template that is close to what I’m looking for that I could mess with. I’m a pretty good hack, not a great programmer and I’m very new to wordpress.

It looks so simple, I think there has to be a basic 3 column template and a few plug ins that could make that template in seconds.
