Default 3 LEDs and 3 Switches..

Hi all.
Can anyone give me a diagram or help on how to do this..
I've got 3 LEDs, and 3 Momentry Switches.
Id like to make it so that 1 LED is on at all times.
eg.
123 - ABC
Press 1 and A Lights, BC off.
Press 2 and B Lights, AC off.
Press 3 and C Lights, BC off.
And so on. Defalut would be 1-A when inital power up is done.

I could do this dead easily with small relays, but Im trying not to use
them. Idealy it would use Transistors or a small chip.
The source is +5V fed from a 7805
Im trying to get away from the old Clicking way of doing it. !!

Any help on this would be very welcome.

Here is what its for.

Wombat.
