It's a little more complicated than you may think. Making a layout is one thing, creating is far more complicated. Why? There are so many ways to do; different languages, styles, etc. Now, it's hard to explain this accuratly, for I cannot see your illustration, so I don't know how your website is set up.
But, let's say your website looks something like this:
http://www.columbiawestcap.com
It has a banner, navigation, and content.
To accomplish this in one of the most simplest ways is this -
This is your page's title
Your banner image here...
This is the webpage's content
This is about as simple as I can clearly make it. To literally make a link you type the following:
The Link (substitute "thelink" with the actual link.)

Good luck!
