If this minor variant works:

   (apply #'call-process "c:/bin/gnuwin32/bin/find.exe" nil
     (get-buffer-create "output") nil '("c:/emacs/trunk/lisp/" "-name"
     (shell-quote-argument "*.el")))

it might give you a clue to the solution.  The call to
shell-quote-argument should be limited to Windows only, since the
Windows implementation of the library function called by call-process
constructs a single command line out of all arguments, which of course
means you need an extra pair of quotes.
