Serious Question for Experienced Developers

Hello, everyone. I''m representing a small but dedicated group of amateur developers. We have a tentative two year development schedule for our product, and serious coding may not even start until late January. Here''s the dilemma: I am serving as primary director, and I have absolutely no programming experience whatsoever. However, we''ve got a great coder working with us, and he is responsible for assembling his own crack team of hotshots. This is a two dimensional engine, and I have very specific ideas on how the play mechanics will function. Now, I want to present my ideas in an interactive form. I feel that these visual and playable aids will be absolutely necessary in order to prevent a lot of miscommunication further on in the development process. I''m creating very specific sequences: one might resemble the game Frogger, while another would simply present how the player character functions in a given environment. Our programmer acknowledges that these aids would be immensely helpful for him and his team, but worries that the time I spend learning one of these "languages" would ultimately go to waste. I believe there are three primary options: 1) Flash - popular, apparently easy to learn 2) BlitzBasic - has been recommended to me by a number of people 3) KamiSoft applications - ??? Now, which of these do you feel is most appropriate for someone of my experience? Learning curve and program capability is are major factors in my decision. -JoJo
