a cool project.. when i was experimenting with ASP .NET it is best IDE for ASP .NET and totally free...
I found SharpDevelop recently, and your project even more recently.
As this system is some kind of PHP.Net coponent (companred to ASP.Net) is it possible to imagine to use SharpDevelop aka know as #D to make PRADO applications ?
#D is an open source "Visual Studio.Net" for the .Net framework.
It already support php files, but theyr is actually no template for PRADO nor support.
I think it should be one of the best GUI to write PRADO code.
