Alright, this is the whole situation:

A friend and I are going to develope a website. He's going to work on the front-end, which is basically all the design part, and I will work on the back-end, i.e, any and everything related to coding and databases. My friend does not know how to create a site using anything else except for Adobe Dreamweaver CS 3 and 4! So, I decided to let him create the front-end on Adobe Dreamweaver, and I shall put in the necessary code.

Oh btw, yes it is possible to use C# and various other languages while creating a website in Dreamweaver.

What I need to know is, where exactly do I start?
