User-friendly Jenkins CI job schedule format

I'm considering using Jenkins CI basically as a job scheduler. I'm planning to let the end users create, update and delete jobs. The main hurdle I can see is that job schedules are specified in cron syntax which is perfectly un-user-friendly.

Anyone know of any user-friendly scheduling plugins out there? Something like the windows event scheduler (see below) would do.

Alternatively, are there any other (Windows) scheduling solutions out there that I should be looking at? I looked at a bunch and Jenkins seemed overall the best for our needs:

• half-decent web-based UI out of the box (preferably skinnable)
• small number of users
• small number of jobs
• flexible
• relatively lightweight, low-overhead
• has a Web API for programmatic access

For the record we're a Windows / AWS / C# / MySql / JS shop. With some Java. Linux isn't an immediate no-no either.

Thanks in advance, Pete
