I want to make a simple multiplayer web browser strategy game.I don't care about graphics,I'll just use simple pics.What tools/programs should I use? I don't want to use Java....

I would say java and flash, but since you dont want to use java, you could try ... perl/html and flash. Java would make it easier I think -- but I dont have much experience in web based multiplayer games. Theres probably a nice combination of .NET tools you could use-but I wouldnt be the one to ask about that.
