Something like (quick hack):

cat historyfile | awk '//{x[$0]++; } END { for (k in x) { print x[k] "
   " k; }}' | sort -k 1rn,2 | cut -f 2- | dmenu >> historyfile

The input is read from X, not stdin, but if you mean additional input
apart from the history file you can append it and probably use some
kind of "weights" (like used count), then after it use sort like
above.
