I don't think the latest amiga version of Kaffe is/was
the 1.0.7 I think it was 1.0.3 (at least that was working on the amiga, and 1.0.3 was only so-so at that time).
unfortunately I think kaffe needs ixemul so currently
a OS4 native version looks slim.
and I would also suggest going for the PPC version
directly if you can (the ixemul reason) since otherwise you are still stuck with doing that later on and it won't be easier then (albeit you will have learned a lot about kaffe by then :-) )
if you are also thinking about making a awt kinda thing there is several open-source projects that deals with that kind of things.
