Okay gathering inputs from all the replies above., I think the best way to
move forward would be to implement a --method=<GET|POST|PUT|DELETE>
followed by --post-data or --post-file in case of POST and --put-data
--put-file in case of the PUT option.
In other cases wget expects the URL next.
The GET option is included only for completeness.

Please do let me know if I'm missing something.

Also, as Tim pointed out, wget does not test whether the file exists. I'll
patch that too.
