The main problem you will come across using Glib::Dispatcher is passing
data to the callback.  For that, it is best to use an asynchronous
queue.

In another posting you said your program does a lot of input-output.
You don't need threads just for that: you can set up a watch on a
file descriptor for the main GUI thread using
Glib::signal_io().connect(). GIO/giomm also has a wide range of
asynchronous IO functions where all the hard work is done for you.
