D - How? Callbacks from GTK+

I need help here. After following D for the last year I just spend 4 hours with D and 4 hours with GTK+ on linux and I'm coding a D wrap for GTK+ obviously I'm calling it DUI. It's a child's play except for the callbacks (signals?). I read the old posts on callbacks and delegates and I still have no clue on how to get the callbacks to work beside creating a static function for each callback, for each widget instance. Is there a better way (I sure hope so)? Can anyone help? (Yes, I have to say that I never worked at this low level.) My first idea was to have 1 callback per GTK widget (or widget class or...) that would then call the appropriate D widget, unfortunatly I don't think I can set my D widget pointer on the GTK widget. Is it here I can use and array of delegates? Do I need browse all the D widgets until I find the correspondence to the GTK widget that generated the callback? This would imply mantaining a table with all the D widgets, doesn't sound like a good idea... (hope this makes sense) If you are curiouse on my DUI implementation: It's a prety simple job, just typing in D classes that wrap the GTK widgets. For sure it will not be the definitive D graphic toolkit but it will work, no doubt after just a couple of hours I have a top level window and buttons and text entry. My experience is manly java.swing, I did look at other X toolkits many year ago. Thanks Ant
