What's wrong with using "run"?  I.e., something like
C:\cygwin\usr\X11R6\bin\run.exe /bin/bash.exe --login -c "ssh -f -Y -A remotehost xterm"

BTW, a couple of caveats: you'll either need xterm to be in the PATH on
the remote host or specify the path to xterm explicitly; DISPLAY has to be
set properly; and you might want to redirect the output of ssh to a log
somewhere, just so you know when something goes wrong.  Here's what I have
that's worked for me just now:

C:\cygwin\usr\X11R6\bin\run.exe /bin/bash --login -c "DISPLAY=localhost:0.0 ssh -f -Y -A user@remotehost /usr/X11R6/bin/xterm >/tmp/invoke_xterm.$$.log 2>&1"
