Is that because flip-flops require capacitors to store state information? I
would be interested to know the minimum complement of components necessary
to support a single flip-flop. Perhaps there is a good link to this kind of
information (?)

I have a similar request as the original poster. I would like to use a
momentary switch to cycle among three LEDs. Is the circuit design for this
using flip-flops complex? Is there an easier way to generate the same
functionality? It seems that there must be some ICs out there that provide
this kind of functionality out of the box. Does anyone know of any?

Thanks a lot!
