If you ignore some of the documentation, you can do this...

pro loop,ev
common ctl,ok,button1,button2,base
if ok eq 1 then return
ok = 1
i = 0
while ok do begin
i = i + 1
for j = 0 , 100 do void
widget_control,button1,set_value=string(i)
;
event=widget_event(base,/nowait)
; ^^^^^^^^^^^^^^^^^^^^^ Lets IDL find out whats going on in the world.
end
end
pro ender,ev
common ctl,ok,button1,button2,base
ok = 0
widget_control,button1,set_value='start'
return
end
pro starter
common ctl,ok,button1,button2,base
ok = 0
base=widget_base(/row)
button1 = widget_button(base,value='start',event_pro='loop')
button2 = widget_button(base,value='stop',event_pro='ender')
widget_control,base,/real
xmanager,'',base
return
end
