Yes, the functions you describe are available as gdk_input_add:

	gint gdk_input_add (gint              source,
			    GdkInputCondition condition,
			    GdkInputFunction  function,
			    gpointer          data);

and as the name suggests its part of GDK rather than GTK (it's in
gdk.c): source specifies the fd, condition is one of GDK_INPUT_READ,
GDK_INPUT_WRITE, GDK_INPUT_EXCEPTION, function is a pointer to the
handler and data specifies callback data.
