That seems like something that should be fixed.  The -c option is short
for --create-frame. This is something that Emacs on Windows can do,
regardless of whether it supports the --display argument, multi-tty
or daemon mode.

As far as I can tell, the problem is in emacsclient.c, where it sets
tty = 1 if --create-frame is given without a --display argument or
DISPLAY environment variable.  Windows then fails to create the new
frame because it can't create tty frames.  Either the code in
emacsclient should be changed not to send tty = 1 on Windows, or the
code in server.el should be changed to ignore the tty option on Windows.
