Is there a graphical GUI builder?

[Rex Macey]

I'm new to Python and only a hobbyist programmer.  A long time ago I used Microsoft's Visual Basic which had a nice (graphical) facility for creating GUIs which was part of the development environment.  I'm wondering if there's a utility for Python to build GUIs.  I see that there is TKinter, which is a scripting function to build GUIs. To be clear, I'm looking for a graphical interface to build GUIs. Thanks.
