Ruby IDE similar to Visual Studio?

I want to know if there's an IDE for Ruby who's similar to Visual Studio where there is a toolbox and we can do Drag-and-drop tools from the box and place them on a windows form, I tried IronRuby and Sapphire for my Visual Studio 2012 and tried with Visual Studio 2010 too, but it's not working. When I want to launch the application in Visual Studio 2010 or Visual Studio 2012, I've got the error : Flash Forms Compiler failed with exit code 6
