   Examples of HDBC in 'Real World Haskell' and Gtk2Hs tutorials are 
sufficient, but database application with GUI it's different story. It's 
all about model/view/controller. Gtk/Gtk2Hs approach is like this (using 
model/view): get data from database and then duplicate them in the model 
(Gtk calls the model 'store'). This is unacceptable in real world 
application. There is a way, I can create my own custom model (and 
implement all this myself). This is the way to go, but unfortunately 
there is lack of examples. Modev/view/controller 
(TreeView/ListStore/TreeStore) provided by Gtk is useless in database 
context (unless one implements all missing functionalities with custom 
store).
