You are free to implement the GnucashWritableFile -interface using JNI
and the Gnucash libs.
Just make sure to follow the contract of that interface and please
provide your binaries for more then just Linux-i386/x64 and 
Windows x86-32/x86-64.

I can write some more unit-tests to validate it if you want.

There is practically no code you can reuse in Gnucash itself
as it all depends on the Plugin-API (requiring things like
introspection), the JavaScriptingFramework (so users can customize
things using Javascript, php  and a few dozen other scripting languages)
and the inidivial plugins are build on things like HBCI4Java, Javamail,
... just what you usually use when writing such a helper-application
in Java. I don't know if there are equivalent libraries for C/C++
at all.
