Sorry but, if your new to modelling... you are best starting with a program that a)
has a help file, b) has a full set of tools, c) has a large enough user-base to ask questions for.
while I'll once again echo, easiest is subjective. there is such a thing as 'User-Friendliest', programs like that will be the best to start off with.
3D Studio Max, Maya, and trueSpace. I would consider straight-forward with good User Interfaces.. each one is easier and more understandable more based on your personality really.
Personally I consider Maya
pick-up'n'play, for the simple reason everything you need to begin with is available with icons that are pretty descriptive not just in thier images, but also with the names that pop-up. It doesn't take long to figure out how the basics work. Once your confident enough the help files is EXTREMELY extensive.

Just unfortunately more reading that seeing.
