Since nobody seems to have already done this, I thought I'd add the
snippet for the archives.  This uses a slightly older version of
Win32Lib, so there may be some broken code with the most recent version.
 It also uses some routines from DateTime.e - Routines for handling Date
and Time - (c) 2001 CyrekSoft.  Use it or abuse it as you will.

---- Code follows ---

procedure draw_month(atom month, atom year)

  atom TOPLINE  -- constant defining the height of the header line
  sequence MONTHS  -- constant list of month names

  atom dow, dim    -- the day of week the month starts on & # days in
month
  atom curdow      -- current day of week used in drawing the days on
the cal.
  atom curweek     -- current week in drawing the days on the cal.
  sequence canvas  -- the drawable area

  TOPLINE=32
  MONTHS={"January","February","March","April",
                   "May","June","July",
                  
"August","September","October","November","December"}
