Mine is Qt.

I am developing an admin client for PostgreSQL: pgXplorer (github.com/davyjones/pgXplorer). I was coding primary on a Windows platform and decided at some point that a Linux build would be useful as well. I was surprised when the project compiled the first time I imported it into my Linux environment, and that too without any tweaks. So yeah...more than surprised actually.

But...there are some issues I am facing with window behaviour, mouse events, etc. Still working on that.

We use QT extensively at work. It is the best documented framework that I have ever worked with. I am primarily a C programmer who dislikes GUIs, but the it has made GUI development pretty painless for me. Their networking classes are also good.
