Hi Joel,
it is correct that IB does not offer a C++ interface on UNIX.
Given these circumstances, and given your wish to write completely portable
code, I would agree that development in Jython/Java might be your best
option. JNI is definitely not advisable for your purpose; it is Java's
method of dealing with platform-dependent ("native") code which is exactly
what you want to avoid.
You would then be using either Swing or Eclipse (but not both as they do not
mix well) for GUI and graphics development. These are excellent Java
libraries, and a friendly war is fought between the two camps. Swing, being
pure Java, is completely and totally portable. Eclipse uses native widgets,
which may look a little more familiar to the user of an OS. Eclipse has not
been implemented on all OSs; however, it does run on Windows, Macs, Linux,
and QNX.
If you decide on using Eclipse (http://www.eclipse.org/), it comes with its
own free GUI designer built-in. If Swing (also free, and an integral part of
Java), you have a choice of GUI designers. The one most popular with
professional Java developers is IntelliJ's IDEA
(http://www.jetbrains.com/idea/index.html); unfortunately, it comes with a
$499 price tag, but it's well worth it. Saves one untold hours through its
many nifty features. (No connections etc.) One free GUI designer for Swing
would be NetBeans (http://www.netbeans.org/) which is good, but a little
unwieldy.
All the best wishes,
Michael Suesserott
