Hi, I Made A Mod Here(Forge), It Started As A Util In A Mod I Already Made Then As It Progressed I Turned It Into An API!
It Is Not Only For Beginners, I Myself Use It In Almost Every Mod Im Working On!
It Provides A Simple Mod Library Witch So Far Has:

A "doRender()" Function For Blocks And Items Witch Renders Them In The Usual Way,
Starter Item Tool Classes,
Custom Creative Tabs(That Are Already There And For You To Make),
An Ore Tab An Egg Tab And A Portal Tab,
An Entity/Egg Registerer(Has Issues),
Mob Rendering Classes:
RenderMob(Model, Texture),
RenderMultiTexture(Model)(Is Abstract, You Have To Make The Texture Picker),
RenderTameMob(Model, TexUntame, TexTame),
RenderModWolf(TexUntame, TexTame, TexAngry)(For Any Wolves Used In Mods),
A Do-Nothing Item Class,
A Do-Nothing Block Class,
Enjoy!
