In order to recreate this layout, you will need to learn a variety of concepts.
First, how to style an unordered list ( <ul><li> ) to work as navigation.
Second, you will need to learn how to position elements, either through using float:left|right or position:absolute|relative.
Finally, and perhaps most importantly, you will need to learn how to use either Google Chrome's Developer Tools or Mozilla Firefox's Firebug, as these are indispensable tools for reading and writing html/css. Specifically, you will need these tools in order to inspect the code for other websites to see how they implemented their design. This is perhaps one of the best ways to learn code (at least it was for me).
Providing a detailed description of how to do all of this would take too long and really detract from the valuable learning experience you will get from googling, fiddling around in the original source code, and trying to recreate it in your own site. If at any point in that stage you have trouble implementing something, then by all means come back to stackoverflow and ask for help :)
