If you take a look at my web page: www.kennethgreen.net, I used After Effects for the animation. I then exported to Flash [as a movie]. I placed where buttons should be and included VERY simple Action Script commands, and presto, a moderately interactive menu. I obtained basic Flash knowledge in college. All in all, it's very simple.
Also, if you look at

They used the same concept I did. The designers give the illusion that this is complicated Flash interactivity and design. When in essence, all they did was design and animate in AE, Maya, etc. and then export as Flash movies. Threw in some roll-over button scripts [which you can look up online] and there you have it.
