I'm not sure if this is what you want but check out this thread

http://www.stata.com/statalist/archive/2003-03/msg00070.html

using that as a model I wrote a dialog box/ program where values of 
spinners

 SPINNER    sp_q1_r1        @        spyincr    splen        ., ///
     label("Spinner one") ///
     min(0) max(1000) default(30) ///
     onchange("program spq1_chg")
....

if changed, call a program at the bottom of the dialog file

PROGRAM spq1_chg
BEGIN
put "prspin 1 " main.sp_q1_r1 " " main.sp_q1_r2 " " main.sp_q1_r3 " " ///
   " " main.sp_q1_r4 " " main.sp_q1_r5 " " main.sp_q1_r6 " "
stata
END

which then builds a command line and invoke stata to run an ado file 
called - prspin.ado

the ado file does some calculations and then returns a value into 1 of 
the six spinners
with this statement

.prevrev_dlg.main.sp_q1_r6.setvalue "`val'"
(using the class system to set a label or value in this case)


a pretty specific operation but it might be generalizable to what you 
are interested in.
