Is it possible to make crossplataform "all in one" executables?


I’m very interested in Electron. :slight_smile:
But I would like to know if there is a way to make all in one apps or I will need to use to packagers like AppImageKit?

Some thing I’m looking for is ability to execute internally other executable, or automatically extract it to somewhere else.
I’m thinking in porting some Java + fortran programs to it and, apart from the fact those java executables execute in both Linux and Windows without a installer with just a file, electron is perfect and even solve other problems I will be glad to leave behind.
