Each four component should behave the same. In pratice, each one has its 
own quirks, GTK+ components being less tested than QT ones. It depends 
on what you use exactly, so just try or ask.

Normally, you should use the gb.gui component. It will choose the 
toolkit according to the desktop used by the user, and the components 
actually availble on the user desktop.

Choose explicitely a component only if you encounter problems with the 
others.

The first package is your program. The four others are dummy packages 
that just introduce the dependency on each GUI components.

It's up to the user to choose which one to install.

The problem is that there is no way in debian -as far as I know- to tell 
that one of the four packages must be installed. You have to make them 
all optionals.
