Command line utility to write to Google Docs Spreadsheet

I need a command line utility written that does the following: 1) Accepts on the command line ---- host name of mysql machine ---- username and password of mysql account ---- a SQL select string ---- the URL of a google docs spreadsheet (will already exist) ---- credentials for the google docs spreadsheet 2) Issues the SQL string to the MySQL database 3) Erases everything in the google docs spreadsheet -- EXCEPT for the first row (which is a header row) 4) Writes each row of the SQL results to a row in the spreadsheet Then exits. The utility should be either 1) A groovy shell script or 2) Java code that compiles down into a self-contained .jar file
