The latter.  You are allowed to use it without being charged by the gtk+
people.

However, you need to abide by the rules in the license, basically including
allowing your application to be dynamically linked against a different
version of GTK+ and supplying source code to GTK+ if you supply the
libraries (but not source code to your own application if you don't want to)
etc. etc.  Read the whole license for full details.

No that's not true.  Tor Lillqvist (amongst others) puts a lot of effort
into maintaining the support under Windows, and makes pre-built libraries
available at:

    http://www.gimp.org/win32/

Apparently, there are one or two things that don't work quite as well, but I
have a complex application that works identically under Linux and Windows
without any real problems.

Don't know for this last one I'm afraid.
