Bulak, 'South Brabant' most certainly isn't a province in Belgium. 'Brabant' was a province, but the 4th federal state reform in 1993 changed that, and in 1995 Brabant was split into 2 provinces, a dutch-speaking one, and a french-speaking one.
This is the list of Belgium's 10 provinces (alphabetically, grouped by state), with their capital for reference.
Flanders:
Antwerpen (Antwerpen)
Limburg (Hasselt)
Oost Vlaanderen (Gent)
Vlaams Brabant (Leuven)
West Vlaanderen (Brugge)
Wallonia:
Barbant Wallon (Wavre)
Hainaut (Mons)
Liège (Liège)
Luxembourg (Arlon)
Namur (Namur)
Brussel(s) is it's own state, and is one of the most hotly debated topics in Belgium. Technically surrounded by Vlaams Brabant, both the flemish and the walloon people claim it as theirs.
The final, and only point I'd like to make is this one: In Europe, there is more to classifying people than just asking them their home nation. Ask anyone from Corsica, Catalonia, Limburg, Sicily, Northern Ireland, Bretagne, Kosovo, Basque and who knows how many other regions. Nations are merely groupings of regions, held together through historical force of arms (i.e. conquered by, or liberated from, some, usually external, force). It is the true future of Europe to abolish these straight-jackets, and finally ensuring no group of people in Europe will ever try to dominate (or exterminate) any other group of people in Europe ever again.
