there seems to be some confusion. of course this is blocking - GTK is an
event-driven GUI framework, and so the core part of your program is a
loop that sits and waits for events and asks your code to respond to
them. Gtk::Main::run() makes this easy for you.

in your case, you seem to want the code part the program to be a loop
that waits for readline/tty input and then responds to it.

not going to work (without some odd hacking). you're mashing up two
different styles of programming.
