It is possible and well done since GTK+1.x, which I#m using:

Have a look at the API docs (GTK+/GDK Reference Manual, chapter
"General") and the tutorials:

function names

        gtk_main_iteration_do

        gtk_timeout_add
        gtk_idle_add

        gdk_input_add

may help you searching.

I'm using the last one to listen for event of a controller board with
attached keyboard, this works perfectly well.

HTH,
