1)Download "JRun" and you will run any Class by Double-Clicking... Or 2)Download "ExeJ" and you will have your .jar file to Windows executable... Or 3)Write a program on Java that's executes your commands (but you'll need the dependencies files or jars.)
You will find that on net.
But i am warning you that your source code is not protected. Java belongs to OPEN SOURCE community, so...
I suggest you "EXEJ".
(There are many programms that do your job, but these are fine...)
