Dialog on startup

[Ron Forrester <rjf zero-ping com>]

When my app (gamestalker) starts up, I am checking on a server (via
sockets) somewhere to see if there is a newer version available, and
if so I would like to popup a dialog notifying the user.

Is there some way before I call gtk_main(), I can queue up a message
(signal?) such that once gtk_main() is called, the signal will fire
and I can popup this dialog box?
