Nevermind. I found this website of win32 ports [1] which provides a 
quite nice installer. Before running that installer, I downloaded and 
installed both MSYS and MingW. I tested the build environment with some 
simple programs and it seemed fine. Then I ran the installation of the 
GTKmm for Win32, which also went smooth. Next, I ran the GTK+ demo 
application and was happy to see that it worked as well (I reckon this 
assures my GTK+ runtime is fine).

The final step was trying to build a simple GUI using Glade. I did so 
and, at first, tried exporting it to C++ code, but it failed and showed 
me a message asking me to check whether I had glade-- installed, which I 
do (glademm V2.6.0_cvs). Anyway, I decided to try out my glade file with 
libglademm (which is the way I intend to go in my actual project). So, I 
wrote the following, minimal program:

#include <gtkmm.h>
#include <libglademm.h>

int main(int argc, char *argv[])
{
  Glib::RefPtr<Gnome::Glade::Xml> refXml =
    Gnome::Glade::Xml::create("teste.glade");
  return 0;
}

I tried to build it with:

g++ -o teste teste.cpp `pkg-config gtkmm-2.4 --cflags --libs`

This gave me the error message: "can't find the 'libglademm.h' include 
file". By invoking pkg-config directly, I could see that there actually 
was no '-I' option for libglademm's include directory. Why is that? Is 
it by default? If so, how can I manually change the "package definition" 
so that the libglademm include dir and lib file are included when I run 
pkg-config on the package gtkmm-2.4?

Anyway, by manually adding the include dir and lib file, I was finally 
able to build my simple test application. However, upon the first 
execution attempt, I got an error saying that I needed to call 
g_type_init() before the call in my main(). I did so, but then I was 
bombarded with tons of CRITICAL errors. The initial lines read:

Could anybody assist this newbie in successfully building that simple 
test application?
