Such tasks aren't covered by GNOME really. You should use the standard
system mechanism for this task. E.g open the block device for the
serial port (I believe its something like /dev/tty) with fopen and use it
like a normal file. That's the unix way of doing such things. Grab a Unix
System Programing book for more details.

This is done with Gtk[H|V]Box objects. These are just container objects
which place their child widgets either horizontally beside or vertically
above each other. In your case you want a GtkVBox with two child widgets.
Look at the GTK tutorial at www.gtk.org and/or into the "Gtk And GNOME
Application Development" (GGAD) online book at developer.gnome.org.
