GUI toolkit for rapid development?

Question

I want to write a front-end to an application written in C/C++.

I use Solaris 10 and plan to port the application to some other architectures (Windows first).

Answer 1

I'd recommend taking a look at wxWidgets to provide some cross platform UI widgets that will work on Solaris and Windows.

Answer 2

Qt 4 is the best tool for this job. If you want to work with other languages, it also has bindings for Java and Python
