There is this addon that was built called Window Generator 2. It can be found at this BA thread. However, when I go to the download link it shows up in a new tab as a bunch of code.
How can I download and use this addon in Blender?
.py extension for example..
Open User Preferences (Ctrl+Alt+U) and under Add-ons, click Install from File. Then navigate to the file you downloaded and select it.
It should now appear in the window and you can tick the checkbox in the upper right to enable it.
If you would like to have the add-on enabled every time you start Blender, click Save User Settings at the bottom.
Alternatively, you can just save it and open it in the text editor and press Run Script.
This is an alternative method that works well with multiple file addons as well:
Move or create an addon directory into the addons folder of your blender settings:
Example for Linux and Blender 2.69:
Example for Windows 7 and Blender 2.69:
Example for Windows XP and Blender 2.69:
C:\Documents and Settings\%username%\Application Data\Blender Foundation\Blender\2.69\scripts\addons
Example for Mac OSX and Blender 2.69:
Activate the addon in blender
