Heck, John, the way I look at it:
    If you can't to hack it, you shouldn't hack it.  ;^)

Anyway, just this once .. walk NextWindow starting with screen->FirstWindow,
looking for (Window.Flags & BACKDROP) and (Window.Flags & WBENCHWINDOW).

But I warn you: this window can be closed at any time, so unless you have
another window open on the Workbench (which will keep it from closing), you
can crash the machine real easy.  Also, that window is not your property, so
don't be bummed when your hack stops working with next release, and be
sure not to give your phone number out in case it causes somebody a big
crash and they want to tell you all about it.

By the way, once you have a window on the WB, you can use
window->WScreen->FirstWindow instead of GetScreenData().
