Help: Creating a wordpress theme

Hello!

I’m not sure if this is the right place to ask this question, but I’ve been sitting in front of my computer for many, many, many hours trying to get some answers.

I created a CSS and HTML website via Twitter Boostrap toolkit. (it’s a framework that supplies clean cut CSS and Javascript plugins.)

I’m trying to add e-commerce and I want to take advantage of what WordPress offers.

How should I go about transferring my HTML and CSS files I have to word press?

My layout is as follows:

Header Image

Nav

Slideshow

Content

Footer

(No sidebar)

Fixed width of 960px.

My goal is to create a wordpress theme and then be able to incorporate ecommerce via wordpress. I also want to take advantage of multi-site and buddypress.

But my main goal right now is converting what I have to wordpress, then I’ll deal with that stuff later.

I tried to cut it up and put it in .php files, but I’m having a horrible time.

I’m using a lot of javascript files that are embedded into the HTML file and I’m using some inline code to override the external CSS style sheets.

My layout seems simple enough but I cannot find a matching theme and I really would like to convert what I have to wordpress.

I know HTML and CSS very well, but I know very little of PHP.
I even suffered through an entire lesson on lynda.com on how to create custom themes, but after an hour of lessons, I didn’t learn anything.

I was thinking about using the twenty eleven theme, but idk how to make the header a slideshow…but that might not even be a solution for me!

Please help D:
