Yes, code after your "not work" follows:

[...]

/* this will work */
call Notify("progress","CloseRequest",1,"app","ReturnID","QUIT")
call Notify("cancel","pressed",0,"app","ReturnID","QUIT")
 
  return

/* this is the function i want to leave, pressing the button */
lets_go: procedure   
call set('win','Sleep',1)
call set("progress","open",1)

DO cds=1 to 10000

/* you have to call NewHandle() but don't wait for any signals */
h.NoWait = 1
call NewHandle("APP","H")
/* The only QUIT can be the Cancel-Button or the Close-Request */
if h.event="QUIT" then leave

  /* counter for progress bar */
  percent=trunc(cds*100/10000)
  call set("gauge_glob_progress","Current",percent)
    call set("gauge_glob_progress","InfoText",disk_nr" CDs found:" percent||"%")
    call set("gauge_glob_progress","ShowMe",1)

  END
  call set("progress","open",0)
  call set('win','Sleep',0)
return
