I am not very good at making 3d models, so is there any software out there that makes it easy and quick for people like me?

Cosmic Blobs. Hehehe.
Jk. Try your hands on something like Google SketchUp to get you used to it. Then if your a student somewhere you get student editions of the Autodesk software.

If what you're asking for is a piece of software that generates a 3D model of whatever you want, well, sadly there's no such thing yet. 3D modeling is an art and a science, just like sculpting. It's something you have to learn by practice and at the same time something you may never figure out (it requires talent, at least for less technical stuff like humans, animals etc.).

Bad news being said, let's get back to business. You could try Blender, people say it's easy to use, though I personally find it more difficult than 3D Studio Max. You could also, like KingLuke24 said, try Google SketchUp, as it is a pretty good way of getting used to a 3D environment and basic modeling tools. If you feel artsy and creative, you should definitely take a look at Sculptris.

milkshape, it's the simplest tool Ive ever used...And the ease of writing yer own plugin is soo relieving

I've found Wings3D fundamentally similar to Blender for the task of making UV-mapped polygonal models, but far simpler and with a nice user interface (it doesn't do anything else, so it can be specialized and clutter-free).
