Glade is a user interface composer tool. If you're asking if you can use the results of what you create with it as a replacement Windows Shell, the answer is theoretically yes. It does still require all the Windows API libraries to be included in your install since as I said, GTK+ on Windows is built against the Windows APIs. If you want to use Glade itself as a Windows Shell, you probably can, but it would be unwise. This version of Glade was somewhat fragile--it was not difficult to crash it.
Not sure what you mean by "boot". This version of Glade is very old and obsolete, but should simply install by running the installer in Windows 7 or XP. It does not run without Windows running first. It uses the GTK+ libraries which are compiled for Windows GDI. Without them, it won't run, so it can't be "booted" as such.
The installer script is long lost, many years ago. I never checked it in and lost...
