Wordpress is the Content Management System smashill is build on. The theme is handcoded, which is a great way to go in case you have a small budget. Now I am far away from being a tech geek, I find my way around certain things, but I am not good at coding! The great thing is there are resources that will help you coding your own wordpress theme in no time if you have some basic understanding of html.

The best tutorial on coding a wordpress design can be found at the no longer updated blog wpdesigner. It used to be a great source of information about wordpress until he sold it, but nothing happened after that sale. So who knows what happend there.
Anyways the site is still up, so do yourself a favour and grab his very detailed tutorial.
First of all he describes how to design a theme using photoshop, then he describes how to slice that design and finally how to code that design to create a wordpress theme. Each and every of those tutorials is pure gold for someone wanting to create his own wordpress theme with little knowledge about php or coding in general. Get them as long as the site is up and running

Prior to this wpdesigner wrote a tutorial series that can be accessed at the blog, but the pdf’s are far better from my point of view, nevertheless it’s the second best resource on how to create a basic wordpress theme.

In case you take your wordpress theme a step further, there are now other great resources about design and how to alter your CSS code to improve your overall site experiences, for example CSS Tricks. One hell of a great article is How to take wordpress one step further from Function Web Design.

In case you are simply thinking about creating a portfolio site, or a non wordpress related site, or a wordpress theme with a grid structure, check out Typogridphy or the 960 Grid System. The one is based on the other, but both are flexible and interesting foundations for good looking websites.
