There are two main approaches: - use async APIs that integrate with the glib main loop (e.g. Gio has classes for talking to sockets/subprocesses, which is low level, then there's Soap that gives you a higher level async HTTP wrappers.) - use threads, being very careful never to call GTK+ APIs from them directly (use GLib.idle_add() to register callbacks to be executed from the main thread, whenever a background thread does something interesting that needs to be reflected in the UI). https://wiki.gnome.org/Projects/PyGObject/Threading has examples of both threads and using Goo.File.load_contents_async() to download a file over HTTP asyncronously.
