glib doesn't require X.  It's really just a library of useful things,
like
a nice generic hash table implementation and some nice generic linked
list
implementations, some sophisticated memory management techniques, etc.

About booting from floppy...  Let's see:

[jasonf@eraserhead jasonf]$ mkdir /tmp/slime
[jasonf@eraserhead jasonf]$ cd /tmp/slime
[jasonf@eraserhead slime]$ cp -ap /usr/lib/libglib* .

So it would take up approximately 53K on a compressed boot disk image,
and it
doesn't require any libraries other than the C runtime library and the
linux
loader.  I could make that work, no sweat.  Hell, I probably have room
left for
GTK+ and TinyX ;-), and you wouldn't need a window manager if you're
only running
one program.  (If you play your cards right with compression and kernel
size, you
can about a three megabyte root filesystem on a floppy).
