Lookup Gui Color for GTK

BlitzMax Forums/Brucey's Modules/Lookup Gui Color for GTK

The LookupGuiColor Function doesn't work with the GTK Module.
I know that nobody is working on the GTK Mod anymore, however is there a way to get the gui color of the window.

Or would it be hard to wrap it somehow?
