I am the author of DockBar. This is taskbar like applet for Gnome desktop environment.
http://gnome-look.org/content/show.php?content=97822

In the process of creation of DockBar I've found a big problem in that there is no perfect way to found .desktop-file for launched application.
There are several ways to do it, but they are all far from perfection and not always works.

There are some troubles in creation such programs (like DockBar/AWN/Gnome-Do/etc....) because of the above mentioned problem:
- hard to find normal icon
- hard to find localized name for app
- hard to use launchers

Please take a look to launchers in DockBarX

Users need to enter wm_class by hands.

Or take a look to Gnome-Do's sources
E.g. http://bazaar.launchpad.net/~do-core/do/0.8/annotate/head%3A/Do.Interface.Wink/src/Do.Interface.Wink/WindowUtils.cs
There is list of commandline prefixes and so on to find .desktop-file for application.
