  Sure.

  Wrong.  GTK apps do look with native look and feel.  For Windows,
look at the screenshots from the wimp project

http://gtk-wimp.sourceforge.net

  I am sure about Mac too, as I have seen screenshots before (probably
linked from GTK homepage)

[You may better download download pygtk from windows from the link
given the pygtk faq page]

  Of course.  Have looked at libglade ( is availble as glade module in
pygtk).  You can even write a small function to autoconnect functions
to events.  Say you can write function in a format like
  def on_button1__clicked(self,button):
      "This function is called when button1 emits 'clicked' signal"

  ... stilll many more functions like this ...

  and you can even write your own function that autoconnects functions
with their object/events.

  Instrospection in Event Handling!

   Sure.  Also have a look at the GtkExtra (also pygtkextra) project.
Writing new widgets is also pretty neat in PyGTK.

  If not, you can try them yourself

  But, those people wouldn't have used PyGTK (or GTK) before.   Don't
get a mind-shift just bcoz of some famous personality has said it. 
Usually I will try out the possiblities and then choose from the
domain.

  As I said before, look at the screenshots. Or see this,
http://gtk-wimp.sourceforge.net/screenshots/

Gimp in WinXP

  PyGTK apps were little slow in Windows.  But since the Wimp theme
(http://gtk-wimp.sourceforge.net) uses native win32 api calls to draw
widgets it should be pretty fair when compared to normal win32 apps.

  Also try the tutorial at pygtk site

  Also see http://developer.gnome.org
  And very important try Glade, the GUI builder which generates XML
files which can be given to the `glade` module of pygtk to build GUI
dynamically.

     May be.  But you can't say that as the best, without looking at
other toolkits.  I found PyGTK great.

> (b) PyGTK is widely used for Unix Python programmers?

    GTK is widely used in the UNIX world!  That's true.

   Happy programming.
