You are EXACTLY the man I've been looking for!
Thank you for volunteering. I will send you the pictures about you can make the buttons. The tech tree... well, I think I can do it, but help is appreciated. The pedia.... yes, the pedia is where I need help. If you can really help as you said, this mod will be wonderful!
I already did a looot of things.
(I already modded the dll a bit: to not to have 18 but 30 as max number of civs, I created the flags, the civs, the leaders, the units, 5 new building graphics, new main menu, new HUD, now working on python scripts, and already changed music (in main menu) and I did a lot of minor changes)
