It sounds like gcj is NOT the right option for you.
Since you mention SWT I assume you are aware of the
eclipse project. They do exactly what you are asking
for. They have a small C program that displays a
splash screen and start the java VM via JNI.

Don't take eclipse's startup time as a measure for
how long it normally takes. They are parsing at lot of
XML files before the actual workbench is shown. I've
tried to do the exact same thing: write a little C
program whose only purpose is to embed a windows icon
(so it looks like a "real" windows program), display a
splash screen and then start a SWT program.
My startup time was below 2 seconds.
