The best way to do this is not to bind a new function to ENTER, but to
redefine accept-line:

accept-line () {
  local cmd=${BUFFER%%" "*}
  [[ -n "$cmd" && $TERM == xterm* ]] && print -nR "executing: $cmd"
  zle .accept-line
}
zle -N accept-line

Replace the print argument with whatever sequence is required for the xterm
titlebar.
