I got several very helpful responses which indicate that travelers have been
able to successfully eat gluten-free in Belgium.  Awareness of
gluten-intolerance and celiac disease seems to be lower here than in some
other European countries.

Suggestions:

Send ahead or take some basic supplies (bread, cereal, snack bars, etc.)
with you.

Delhaize, a country-wide food store chain, is starting to add a section with
gluten-free items.  This website is in French, but can help locate stores-

French and English restaurants cards have been helpful to several travelers
when eating in restaurants.  (Available commercially or free-or-charge on
the Internet.  Google "gluten-free restaurant cards").  In the
Flemish-speaking regions, English was more useful than French.

Many food preparations in the French-speaking area are gluten-free by
nature. Be careful in the Flemish-speaking area - many dishes have
flour-thickened, beer-based, or other gluten-containing sauces.

Belgian fries (frites) are widely available and are usually cooked in
separate fryers, so travelers have found them safe.  Other suggested dishes
are Steak frites and Moules frites (mussels and chips).

Some airlines offer gluten-free meals, if notified ahead of time. (I
reserved this on USAir with no hassle - hopefully it happens that way during
the flights.)

In most countries in Europe, one can also find special dietary foods in
pharmacies. 

Last, but not least - the delicious Belgian chocolates are generally
gluten-free.

Hope this helps others,
