I think the CFUserNotification API is exactly what I'm looking for,
although I'm not pleased with daemons requiring user interaction in
the first place. An earlier reply suggested Growl which I'm thinking
is better suited for what I'm doing. Combined with a simple
preference pane for setting configuration and a CFUserNotification
object for alerts, this should keep user interactions to a minimum.
Thanks for the responses!

A command-line tool, invoked from a logged-in user account, can use
a GUI if it's linked against the appropriate libraries (like
AppKit). As a trivial example, you can launch a regular Cocoa app
from a shell by just running its binary directly.
But this usually isn't a good idea for something that's primarily
meant as a daemon or tool. A better way to do simple alert-style
interaction is to use the API in CFUserNotification.h. This doesn't
require you to link against anything higher-level than
CoreFoundation. The downside is that it's kind of messy to use for
anything beyond a simple "message and OK button" alert; but I think
there is sample code with examples.
