gcj compile issues

Hi,
I have plans to compile (under Ubuntu) Java programs to native MS Windows
executables. I have installed mingw32, mingw32-binutils and mingw32-runtime
as well as gcj, gcj-4.0, gcj-4.0-base, java-gcj-compat, libgcj6,
libgcj6-awt, libgcj6-common, and libgcj-common. I'm using the sun JVM. I'm
running Ubuntu 5.10.
I can compile a windows binary using the MingW32 gcc, and a Java class file
using gcj. I haven't found a good howto for creating a Windows binary from
Java code under Linux. I suspect that there's some classpath issues or some
such to be sorted. Can someone who has done this before point me to the
solution?
Thanks,
Roy.
