I read this request in a dutch forum, and so here I am
Amsterdam is trying to stay as accessible to wheelchairs as possible, But there's a limit to it.
In public transport, most busses and trams are not accessible for wheelchairs, although some new ones try to compensate for this.
Subway trains and stations are better equipped for wheelchairs, but don't expect to much fancy stuff.
Sidewalks are lowered on corners and pedestrian crossings.
Most public places and restaurants are accessible for wheelchairs and most of the time have toilets for handicapped people.
The city centre with it's canals can be a problem as sidewalks are really narrow or non-existent and bridges are steep.
That's about as much basic info I can give you, but if you have specific questions feel free to ask.
You can also try to find more information on www.iamsterdam.com
