How about this?

floatPanel t = className =? "Xfce4-panel" <&&> title =? t --> doFloat

and then, in your manage hook,

composeAll [ floatPanel "Panel", floatPanel "Add New Items", .... ]

Of course floatPanel can be generalized or specialized in a couple  
million different ways, depending on exactly what you want to do.
