Licence for publishing finished executables?

I have recently finished a piece of software and want to publish it as an .exe file so users without Java can use it. Do I run into licencing issues when publishing a version that doesn’t require Processing/Java (I have no commercial intentions with this program). It doesn’t access any java-compilers, so it won’t be able to compile java-code by itselt.

Another question: What files are needed for the .exe to work? I’m sure not every file is needed for the program to run. (I use the 64-bit aplication)
