.Net Like Gui Builder for Python?

[Orochi]

Hi,
This Question may sound lame ,but I am searching for .Net Like Gui Builder for Python.
I tried PyQt Designer' and 'Glade', No doubt its great but it created only interface.
I have to code all the things in separate file.
what I was searching for is Visual Studio .Net like Gui builder where you
drag and drop widgets and just double click on the widget to edit code of that widget.All other formalities of creating a function and class for the main window and widget(e.g Button) is already done.

So,Is there any Gui App builder like Visual Studio or having features like Visual Studio for Python.

Thank You!
