The best IDE for developing cross-platform CAD software
 

Hi,

Where I work now, I'm developing a (closed source) CAD application, but it uses m$ Visual C++ & the MFC library, so it isn't quite portable. I convinced my boss that cross-platform portability is a good thing, but I'm not sure what's the best combination of language + libraries + IDE.

The combination should fit these requirements:
- it should be possible to use openGL
- it should be possible to make a user-friendly GUI
- it should also be portable to window$
- GUI development should be fast & easy
- it should be possible to connect to a database system

We are considering the following:
Kylix
Java
C++ & wxWindows
C++ & QT

Kylix seems to have a great IDE, but it doesn't seem to be portable to all Linux platforms (it's closed source). QT's license seems to cause trouble if you make closed-source apps. Is there a good IDE for Java?

There are a couple of IDE's out there that are available for java. JCreator is very widely used, but (in my opinion) isn't all that great. It also only runs on Windows.

Eclipse is an open source, cross-platform IDE that can be used with Java. It is highly configureable, and is the best Java IDE I've come across.
