Script to generate crontab syntax from pure user-friendly input?

Question

Is there a tool or scripting language that will allow me to generate crontab syntax output after providing a user-friendly specification or initialization file?

For instance:

 when: every 2 hours
 what: system('/path/to/flush_system_logs')

 when: 4:45pm every Wednesday
 what: system('/path/to/system_janitor_script')

I would like to provide such a specification and either have a process that can execute cron from the specification, or create a crontab file that is in sync with the specification.

Here are a few on-line crontab generators:
