Logging certainly works well with PyQt4 in multi-threaded applications, though of course it's based on Python's threading API rather than Qt's. To direct logging output to a GUI, it would be appropriate to develop a Qt/PyQt-aware handler class (derived from logging.Handler) to do the Qt interfacing.
