Opening *Calendar* in its own frame

[Jonathon Isaac Swiderski <jonswid@umich.edu>]

I'm using v20.7.  I've the following in my .emacs to start speedbar and
calendar when in a window system.  Since i was using X11 when I got it from
a classmate, that's what it checks for, although it seems to work just fine
under Solaris 8's CDE.

(if (eq window-system 'x) ; if we are running under X windows...
    (progn
      (calendar)
      (speedbar)))


I'd like to have the calendar be in its own frame.  How can I do this?  I
thought of (make-frame (calendar)), but when I just now did in emacs

M-x eval-expression (make-frame (calendar))

, I got two of them -- one in a new frame, and one in the old frame.  (Yes,
I know they're the same buffer, but that's beside the point.)  Is it
possible to have the calendar just be in the one (newly-created) frame,
somewhat like the speedbar?

And if someone knows of a better way to do the
if-there's-a-graphical-environment check, i'd appreciate tips on that, too,
although I recall reading here previously that there doesn't seem to be a
good way to do it.  Currently the only window-system i use on a regular
basis is Solaris 8's CDE.

Thanks.
