Sorting word list with excel

I need to sort some words with excel but not from A to Z. I need to define the priority myself and sort the word list according to my defined letter priority. Is it possible to define letter priority in excel and sort according to that? If not possible with excel, is there any free software on the net to do this with?

You can do it easily with Excel. Just create a new column for your priority value and sort your spreadsheet by it.

I am not good with excel, can you advice step by step how can I define an alphabet order e.g. like g, k, p. etc. and tell excel to sort the colomns of words list according to this defined order instead of by A to Z order?
