Problem with frontpage

Hi all,

I have a question and hope you experts here can help me out.

Ive made a new website with wordpress, based on the Agile theme. Ive made a static frontpage but i cant seem to add any page sections to this page. This is quite limiting my options on how to make the page beautiful and add some nice stuff. Ive made it a singe page site, but simply no page section options show on this page.
Anybody got any idea on how to fix this, so that i can add stuff to the page?

Hope you can help.
