There are many piece of software that you could use some of the top packages are :

3ds Max (Autodesk),
originally called 3D Studio MAX, is a comprehensive and versatile 3D application used in film, television, video games and architecture for Windows. It can be extended and customized through its SDK or scripting using a Maxscript. It can use third party rendering options such as Brazil R/S, finalRender and V-Ray.

AC3D (Inivis)
is a 3D modeling application that began in the 90′s on the Amiga platform. Used in a number of industries, MathWorks actively recommends it in many of their aerospace-related articles[1] due to price and compatibility. AC3D does not feature its own renderer, but can generate output files for both RenderMan and POV-Ray among others.

Aladdin4D (DiscreetFX),
first developed for the Amiga, was originally developed by Adspec Programming. After acquisition by DiscreetFX, it is multi-platform for Mac OS X, Amiga OS 4.1, MorphOS, Linux, AROS and Windows.

Blender (Blender Foundation)
is a free, open source, 3D studio for animation, modeling, rendering, and texturing offering a feature set comparable to commercial 3D animation suites. It includes features such as multi-resolution sculpting; retopology painting; 3D view texture painting; and other features. Blender is developed under the GPL and is available on all major platforms including Windows, OS X, Linux, BSD, Sun and Irix.

Carrara (DAZ Productions)
is a fully-featured 3D toolset for modeling, texturing, scene rendering and animation.

Cinema 4D (MAXON)
is a light package in its basic configuration. The software is for lay users. It has a lower initial entry cost due to a modular a-la-carte design for purchasing additional functions as users need them. Originally developed for the Amiga, it is also available for Mac OS X, Windows and Linux.

Cobalt

Cobalt is Ashlar-Vellum’s top-level product for 3D modeling and CAD on Mac and Windows. It integrates parametric wireframe, freeform surfacing, feature-based solid modeling and photo-realistic rendering all using the Vellum interface. Everything in Cobalt is history-driven with associativity and 2D equation-driven parametrics and constraints. It offers surfacing tools, mold design tools, detailing, and engineering features. Cobalt also includes a library of 149,000 mechanical parts.

Cobalt is the successor to Ashlar’s earlier Vellum Solids program released in 1998. Debuted in 2001, Cobalt competes with Solid Edge, SolidWorks, CATIA, NX, and Pro/Engineer.

there really is no simple 3D modeling software package but cobalt was the first one that i learned to use it didn’t take me to long.

But if i was you i would uses blender its Free and not that hard to learn (But can be tricky) unlike the others that would put quite a hole in your pocket.

theres lots of tutorials all over the web to help you in complating your project

Hope it helps
