there are numerous databases working under both windows and linux 
(mysql, postgresql, sqlite, ...), there also are numerous GUI 
libraries working on both (see: <http://www.atai.org/guitool/>).

are you sure you want to write this application in Ada ? it would be 
easier to choose a GUI framework in other languages, not necessarily 
C/C++. i wrote very nice GUI applications using python+wxWidgets 
(thanks microsoft for this name, i also prefer the old one), but there 
are many other languages available.

you may consider writing the core app in Ada and the GUI in another 
language, using anything you like to make the 2 work together: DLLs, 
IPC...

you may also consider a Tcl/Tk binding for Ada like TASH 
(<http://www.adatcl.com/>).

there is a list of available GUI framework bindings on adapower 
(<http://www.adapower.com/index.php?Command=Class&ClassID=AdaGUI&Title=Ada+GUI>)
