Word search - free for my site?

hi guys,

im basically trying to make my own word search puzzle for my website.
i would like a ready-made one where i just alter the words to be searched and the subject of finding the words.
it has to be free to alter (another words, the original author does not mind the alterations).
if there isnt a ready-made one available for me to alter, is there a way i can do it myself?
i no absolutely nothing about flash but i wouldnt mind learning it if the wordsearch is a flash version.
sorry if i sound complicated lol… :-/
if you need more help into what im asking, plz let me no

thank you so much
regards
