Have you seen GNUMail.app? It's portable to both environments, so
studying the source could give you an idea of what's involved.

From what I can tell, the most significant difference is that GNUStep
doesn't yet support NIBs. So, GNUMail.app has #ifdefs here and there;
on OS X, it loads NIBs, but under GNUStep, it instantiates GUI controls
programatically.
Thats not right. Of course, they don't support the nibs created with IB,
the season for this is that the nib format is somewhat undocumented and
contains some references to private Ivars of the classes that got
serialized. GNUstep has a own format for that purpose, it is called
.gorm like their IB Clone, the Graphical Objects Relations Manager. And
there is a tool that converts .nibs to .gmodels (another format for that
purpose understood by GNUstep). The reason GORM is not widely used is,
that it is not finished yet, it is currently in alpha state but made
great progress lately.
