Java and Windows are distinct platforms.  I assume you are writing for the 
Java platform.

You can distribute the DFT+ interface you are writing *plus* any parts of 
ASE's source as long as you distribute the whole thing under GPLv2 or

See the FSF license compatibility table for further possible combinations:
