VMware Labs released a new Fling called WebCommander. The download is available as ZIP and is about 1.2MB.
Quote taken from the Fling page:
Have you ever wanted to give your users access to certain virtual infrastructure tasks instead of the entire vCenter Client?
WebCommander is a way to do this! WebCommander was designed as a framework to wrap your PowerShell and PowerCLI scripts into an easy-to-access web service. Now you can hand off the tasks your users need by simply adding a new script and giving them access to WebCommander.
- Windows 2008 or 2012
- Powershell v3 or v4
- vSphere PowerCLI
- IIS 8
- PHP 5
There are additional steps to followed which are documented in the installation and configuration guide.
