GUI Builders For Solaris?

Penguin_99 asks: "I was asked to create two GUI's, in Solaris, in order to compare the speed of a C++ GUI versus a Java GUI. Right now, the GUI builder of choice is Teleuse (which is made by Telesoft), however this tool is hard to use and there is little documentation for it (not to mention the company no longer supports it). I would like to know if anyone in the Slashdot community has experience with Teleuse and knows of any on-line documentation or do you know of a better GUI builder that works with Solaris?"
