Anonymous tkinter/Pmw widgets?

[Christopher Myers]

Anyone know how I can get a reference to an anonymous widget created on
the fly?

Background:
I created a Date-selector widget which is a Pmw dialog with a calendar. 
The calendar is created on the fly, using Tkinter Buttons, and as such,
they are not named widgets -- just buttons placed properly in the
interior of the dialog using the Grid geometry manager and the Python
calendar module for which date goes where.  I suppose I could create an
array of Buttons as use their array index as the name/reference, but I'd
like to avoid that if it's possible.

I want the dialog to return the label on the button pressed, so I can
use that as the date value.

(Note:
Is there any type of calendar widget already written?  I poked around a
bit and couldn't find one, then figured it was pretty easy to write my
own.)

Code snip:

        # Calendar selection dialog
        self.calendarSelectDialog = Pmw.Dialog(master, 
                                    title = 'Select Date',
                                    buttons = ('OK', 'Cancel'),
                                    defaultbutton = 'OK',)
#-------> no command yet . . .      #command=self.execCalDialog)

        # Pack my calendar widget into the dialog's interior
        self.myCalFrame = Frame(self.calendarSelectDialog.interior())
        self.myCalFrame.pack()

        # Build the calendar
        # 8 rows, 7 cols grid. row0 is "Month, Year"
        #                      row1 is Day of Week headings
        # Calendar title, and arrow buttons
        self.calTitle = StringVar()
        self.getDate()  # Fills fields self.y, self.m, self.d

        self.calTitle.set("%s %i" %(calendar.month_name[self.m],
self.y))
        self.calLabel = Label(self.myCalFrame, 
                              textvariable=self.calTitle)
        self.calLabel.grid(row=0, column=2, columnspan=3)
        self.leftArrow = 
             PhotoImage(file="/home/chris/moon/arrow_left.gif")
        self.rightArrow = 
             PhotoImage(file="/home/chris/moon/arrow_right.gif")
        self.calBtnLeft = Button(self.myCalFrame, 
                                 image=self.leftArrow,
                                 command=self.sub_month)
        self.calBtnLeft.grid(row=0, column=1)
        self.calBtnRight = Button(self.myCalFrame,  
                                  image=self.rightArrow,
                                  command=self.add_month)
        self.calBtnRight.grid(row=0, column=5)

        # Day column Headings
        col_cnt=0
        for name in calendar.day_name:
            day_abbrev = name[:2]
            Label(self.myCalFrame, 
                  text=day_abbrev).grid(row=1, column=col_cnt)
            col_cnt=col_cnt+1

        # Buttons for actual days.
        mc = calendar.monthcalendar(self.y, self.m)
        for i in range(len(mc)):
            for j in range(7):
                num = mc[i][j]
                if num == 0:
                    state="disabled"
                    n = ""
                else:
                    state="normal"
                    n = `num`
                Button(self.myCalFrame, text=n, width=2, state=state,
# ----------->         command=self.red_day).grid(row=i+2, column=j)
#
# self.red_day is supposed to turn the day red
# then the user clicks OK.  Optimally, I'd like the button's command
# to return the day selected and close the dialog.
