just an exe that launches the jar index.jar
checks if java is installed in common files,...
I know it already exists but just the simple launcher

it was a stupid question but anyway if somebodys interested, here is the solution:
find a good bat to exe converter, There is one somebody here who made something like that but that tool didn't work, sorry.
I used this one: http://download.cnet.com/Bat-To-Exe-Converter/3000-2069_4-10555897.html
don't listen to some revieuws, they're bullshit
write a little launcher and made it invissible exe with it.
