The best way to create a "one page" theme

Hi,

I’m fairly new to WordPress, and i’m a bit in doubt about a thing.

If i were to make a “one page” theme, something like this: link for WordPress. How would be the best way to do it. There are way to many options, it’s a bit intimidating.

(by one page i mean that when you’re navigating the page the browser do not need to reload the page)

My initial idea was to create a page template for each of the pages, but then again, is it the way to go? If it is, how can i modify the page links to use a hashtag to prevent reloading, and of course trigger the javascript event.

Hope you can give me an idea of what i should do.

Thanks
