You have two main options.  You can set the file descriptor returned by
socket() non-blocking and poll it in the same way as you can poll the
one returned by accept() (certainly you can do that with select() so I
imagine you can do it with Glib::SignalIO which uses poll() under the
hood). The callback will execute when there is a new connection pending
and you can call accept() on the file descriptor and establish the
client connection. This is the way you do it in single-threaded
programs.

Or you can have a separate thread which blocks on accept() and signals
via Glib::Dispatcher that a client connection is available so far as
you need to interact with GTK+.
