jar2exe is commercial software so you would probably need to buy a license.

For your simulation executable you could also consider Launch4j:
http://launch4j.sourceforge.net/
It is free and Open Source and works great - I have used it in several
production environments. 
It has also all the features you might ever need in a professional
application, yet is very easy to use.

The most convenient deployment scenario is to keep your own code in a jar
that will be used to generate an executable while keeping all dependencies
such as the MASON library in a separate sub-folder e.g. ./lib. It makes
managing dependencies for your deployed project much easier. In the proposed
deployment scenario all you need to do is to add lib/* to the "Classpath"
tab in launch4j GUI.

want the jar file to launch your application when double-clicked on or
whatnot, you just need to specify the right entry class in your jar Manifest.
