OK, here goes.
Make a 1m by 1m plane, subdived and tripled to about 1000 polys, move it down
so that the top of the plane is at 0,0,0, and is facing into the +z axis in
modeler and load into layout as your curtain object.

Using fractal bumps in the displacement menu, give it texture size something
like .75, .75, .75; center it to y -1;assign an arbitrary velocity for the
texture (perhaps z -.01)
Texture size and velocity are 2 of the 3 components of your "wind". The 3rd
is amplitude. Try an amplitude of .175 to start. Turn on world coordinates.
Now, here is one of the tricks: you need to set a texture falloff so that the
wind does not blow the top of the curtain. Set falloff to y 1. This means,
since we set texture center to Y-1, that it will displace the most at the
bottom of the curtain, with no displacement at the top of the curtain.

Now do a preview out in layout, you should see somthing that looks like a
blowing curtain. You will now have to play around with the variables to get
the exact wind you are looking for. Also, you might want to bone it to get
more gross action out of the curtain, and by using the new envelope button
for amplitude, you can have a still curtain get caught by a gust of wind, and
the neat part is... by having world coordinates on, as you move the curtain
with a bone back "thru" the "wind", sometimes the displacement make the
bottom of the curtain flip up, which looks very natural.
Good Luck.
