Help me build a website with photoshop?

I dont have much photoshop of web designing experience, but I've taken it upon myself to build a website for my business.

I have a website template which I have loaded into photoshop. The template has four buttons along the top that are supposed to link to the four different pages. I have already designed all four pages of my website, but I dont know how to make the button open up the page. I know i will need to link that button to that page in some way.

once I have my pages linked together, what will I need to do to send it to a hosting company such as godaddy.com or other hosts, and in what format?

At what point in this process will I need to register a domain?

Photoshop is not an HTML editor. It's an image editor. You can design images for the site but you'll have to find yourself an HTML editor like Dreamweaver / MS-Frontpage or learn HTML (it's not so difficult) yourself.

The simplest format for the web will look like that:
1. "index.html"
2. "page1.html", "page2.html", page3.html"...
3. a folder contains all your images.

You can get free hosting services at:
http://www.sitesled.com/
http://www.110mb.com/
http://www.phpnet.us/

These services will issue you a sub-domain like "www.you.110mb.com", and you can even get a free domain registration at:
http://www.freedomain.co.nr/
They will issue you a domain like "www.you.co.nr".

Keep the registration of a domain and hosting services to the end of the process, and use the free services till then.

I've seen some posts of kids who offer to build a simple site for free... I would search Yahoo answers for these posts and contact them!
