Yes, a flip-flop would do it and someone is sure to suggest a PIC, both

looked for alternate action switches or relays? It would run your

Is that because flip-flops require capacitors to store state information?

No.

I would be interested to know the minimum complement of components necessary
to support a single flip-flop.

Just one, the driver.

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?

If you have to ask... Simple for me might be impossible for you, but
you haven't yet described what it is you expect the momentary switch
to do.

Is there an easier way to generate the same functionality?

---
What _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?

---
Pretty much any µC...
