Bear in mind that Qt is C++ and signal/slot based, so
you'll have the
usual problem of integrating GStreamer callbacks using static methods
and the user payload at the calls.
gtkmm is signal/slot based too, but because of its closer integration
with C++ idioms, this particular issue doesn't arise too much. you
don't need a pre-processor to use libsigc++ and if you are working in
C++ for any reason, you should be aware of sigc++. its the greatest
thing for C++ since boost (and thankfully, boost includes something
closely modelled on it these days).
what toolkit you choose, so I'd favour GTK because
of its easy
integration with GStreamer and to keep the whole application under the
callback paradigm.
signals & slots are a callback mechanism too. they just hide it from
the programmer with a different kind of abstraction (when this signal
is "emitted", call the following "slot"). its all just syntactic
sugar.
