Yes it is, I made myself a newton directory where I placed everything in:

newton.dll
newtonsplash.tga
newton.wdl
newtonScript2.wdl
click.wav
door_op.wav
hit.wav

Btw, the newton manual says that I have to add the scripts in WED. If I do so everything works fine but I can't access the actions by script.
