Williams Brewing has a really good Belgian Wit kit that I, my wife and many others were very impressed with. Here is the description of the kit...
Originally associated with the Eastern Belgian province of Brabant, the Belgian Wit (white) style is a fruity, pale wheat beer accented with orange peel, coriander, and other spices. This is a subtle, delicate beer, best appreciated by those who like a refreshing wheat beer with a touch of spice character. The name wit (or white) was attached to this style due to both the original use of unmalted wheat, and to the fact that this beer was brewed without finings, so more yeast than normal remained in suspension.
Includes 8 pounds of our blended malt extract, flavoring hops and spices, liquid ale yeast, and corn sugar for carbonation. Makes 5 gallons with a starting gravity of at least 1.047. Ease of Brewing: Beginner
