I'd say uDig probably makes the biggest effort to make it's plug-ins easy,
with good documentation, and building upon the eclipse plug-in system,
which has many books written on it. And their rendering system is
modular, so I think it could handle a 3D plugin. Also Eclipse 3.2M2 has
opengl support - I don't think they're on 3.2 yet, but I don't think it
would be hard to plug their framework into 3.2.
Another option you might check out is gvSig - http://gvsig.org They have
a pretty good plug-in system I believe. Though their documentation on
writing plug-ins isn't there, as far as I know.
But all the open source desktop GIS systems are still pretty young, so to
some extent it may depend on how long your project runs and what work the
different options have planned. The all have various strengths and
weaknesses, the best thing to do is probably evaluate each for a bit, as a
user, and then try to write a very simple plug-in, and see how hard it is.
