Programming environment selection.

Hi All. I'm wondering what programming enviroment to use for following: GUI interface for user (linux/KDE/Gnome), very basic, nothing fancy. Also I need MySQL access from the SW. Yes, it is mostly a basic database application, and I need also to produce PDF in the end. I can use for example PHP as a script in the end just for converting the final output. I've done it with PHP and Apache, but the differences with various browsers makes it look odd sometimes, and also the limitations of HTML makes it not-so-easy to use. Maybe something like QT or similar? I could try various languages that I have with my SuSE 9.0, but I'm relying on the high level of knowledge among You out there to save time. Jaska.
