The must-see places in Belgium are the big cities, like Brussels, Antwerp and Ghent. Okay, you could also add Bruges to that list. But don't go to Bruges without going to Ghent. The latter has a real life with real persons, not only tourists. And it has a nice medieval castle.
If you want more specific advice, here are 10 interesting things do to and places to visit. If you come to Belgium via Roosendaal, and you want to continue to Luxembourg, all these places are more or less along the road.

I guess you will be traveling by train. This way you are limited to Antwerp, Brussels, Gent and Brugge. Let me start with some tips from my home town Antwerp.
Things to do in Brussels

A very interesting detour might be Baarle Hertog/Baarle Nassau. Here you'll witness a bizar case of borders between two countries Only here you can walk in a strait line an cross the border between two countries multiple times.

Bruges/Brugge is a must see.
As you come from Netherlands, you won't go "Wow" on the bike friendly town. But there are windmills, a beautiful belfry with its carillon that you can visit. There are many canals in this Venice of the North. There are also a chocolate museum and a diamond museum (only the former offers samples to visitors). You can even see the relic of the Holy Blood and the building of the bourse, the first stock exchange in the world.
