Microsoft launched one Internet tool to help SharePoint IT/Dev to help create their Powershell Scripts using Silverlight Application, this tool can be found in this Link: Windows Powershell Builder for SharePoint 2010
You can see the manual here:
Windows PowerShell Command Builder Getting Started Guide
Another useful tool provided by Microsoft will help a SharePoint IT and Developer to send their application and manage the SharePoint sites.
That is great :)
