what best adobe programs to (design) and (create) animated gif or image ?

Hello,

first thank you very much for helping me,

i am about creating an animated gif like the background you can see in war craft 3 frozen throne for a game,

i have to design it first with high quality so i need to know best adobe programs can do that, although i need to know the easiest, so i need to know both of them the best and the easiest so if didn't made it with the best i can made it with the easiest pro, and please put in mind that i need a program to design the image from nothing so i will draw it or design it i don't know depending on the program it self but i will not use it for editing or use an image already there, i need an elite pro that allow to create the image from nothing.

after that i need to create an animated gif for the image (gif not good for high quality images so if you know better please tell),

for example "Her hair moves with the moving wind" so i need to move it, i don't know how so i need a program to make it move too.

last thing at the end i need the file type be accepted in html(5) adobe games programs like flash builder or flash pro for example, i know flash pro can animate it but will not design it, thank you again.
