That's it. 

Formerly, components do not have hard dependencies on other components. 

They just have a file (*.component) that tells the IDE that if the user 
chooses it, then it must choose other components.

I will make a void component (maybe named "gb.gui") that will just load gb.qt 
or gb.gtk depending of which desktop is currently running. This way, an 
application using this component will use the QT library when run on KDE, and 
the GTK+ libraries when run on Gnome. Cool, isn't it ? :-)
