[WIP] Layout - Need Help.

Ok guys, I need a design for the buttons for the navigator. Any ideas?
They will be roller over effects too, any ideas? + Rep to anyone who has an idea.

Also, if there's a way to improve my layout tell me!

(Please note: It is not finished)

Sorry. Didnt inpsire me. Get some colours on there :'(
I feel like 1950s.

As to buttons. A bar of colour with some rectangle buttons on?
And with white text with rollover black or something.
