a gif is just a animated set of still images put to a timespan. If you can create the images you want it is really easy to organize them and export it as a GIF. I build Web applications, but I am terrible at creating images myself. Here is some tools, hope you find it helpful! Also I would recomend looking at Blender, but it would not be a great tool for gifs, but is very powerful and useful for creating still shots to build your gifs with.
