Hi, I am interested in the order :)
I think that converting javas to .exe is a loss of its potential - then it will lose the ability to move between operating systems, and that's its main assumption :)
If you have the application's source code, I will build a .jar file for you that will be responsible for launching the project and its completion after exiting. If you want, I can also convert it to .exe :)
Please contact me via chat.
