[PyQt] PyQt logger

I have a multi-threaded PyQt4 application which has both a GUI and command-
line interface. I am using Qt4's threading because from what I have read, it
is more efficient than the native python threading module. Also, given most
users will probably use the GUI, it seemed to make sense.
I plan to share as much code as possible to the point where the command-line
interface will actually invoke the GUI but the GUI will be hidden and the
command-line options will simply be passed to widgets in the GUI.
I want a flexible, threadsafe logging facility for my application so I plan to
use python's logging module. The main reason I like the logging module is
because I can change the verbosity of logging at runtime. I need a logger
that can log to the GUI or a terminal depending on how the application is
So, my question is -:
Is it wise to use python's logging module in conjunction with Qt4 threads? If
not, what are my options apart from writing my own logging module?
If it is OK, then I would like to know how to subclass a logging object so
that instead of sending output to stdout (as in StreamHandler), it emits Qt4
