shared-libraries

I am writing a plugin for another application. I want to support the plugin on multiple platforms, so I am strongly considering using Qt.

The plugin needs to be able to show some basic GUI. The plugin interface does not in any way handle GUI - it is just a simple DLL/shared library specified with a C-header file.

Can I use Qt inside such a shared library? The calling application might or might not be using Qt itself. Any hints on what to do? Do I need to run a QApplication event-loop in a separate thread? Or can I just call the event-loop myself while waiting for input? (I only need modal dialogs).
