desktop integration: program launcher entry and icon

[Christopher Howard <christopher howard frigidcode com>]

This is not strictly speaking a gtk+ question, but I was hoping someone
might help me out anyway: how do I go about integrating my application
properly with the desktop, i.e., so that my program shows up with an
entry and an icon in the application menu of Gnome, Xfce4, and all other
compatible desktop environments?

If anyone could point me to a good Web page on the subject, I would be
appreciative. I can't seem to get the right search results for this
question.
