Vantage as “onepage” theme possible? Would like to scroll down by hitting a nav button.

Hello everyone.

First of all: im from germany, so my english is not that great. If u dont unterstand something im writing, please tell me!

My “problem”:
I would like to make my homepage in “onepage” style.
That means i would like to post my references, pages and pictures on the main page.
It would be great if the page scrolls down automatically when i hit a button in the navigation bar.

As example: if i push the “Referenzen” button in my navigation bar, the page should just scroll down to a point on the main page where u can see all my pictures from “Referenzen”.

my page: http://www.hd-sign.de

As example, i mean something like this: http://wpdemo.themnific.com/pre/14/

It would be great if u could help me with this.

I think the main questions are:
Is it possible to post pages in the main page with the pagebuilder?
is there an widget to post a picture with some text under it?

Thank you very very very much for every help!!!
