there are attempts to make binary files from the .class file, but
it is convoluted, hard and down right messy.

Besides if you want to make a windows  .exe file  then have a look at C#,
Eclipse isn't bad for hacking toget c# files and it ok for clients that
are only going to be windows clients.

Or write a VB program that runs a command  line "java cp "."
