AFAIK there is no such script and probably even if it existed it would
not be very useful: some of the required changes are trivial and can
easily be done with the features of your editor of choice (e.g. search
and replace gtk_signal* with g_signal), others require instead more
thinking or even rewriting the code to use a new and better widget (the
classical example is GtkTreeView).
Think of it as a good occasion to go through all of your code and give
another iteration at the design of the program :)

There is however a guide here:

http://developer.gnome.org/dotplan/porting/

the guide is a little old, but still valid, you should only also take
care of not using widgets that have been deprecated in versions 2.2 and
2.4 of gtk+ (for example gtk-2.4 introduces the long awaited new file
chooser... somewhere in the docs there is a section dedicated to use it
correctly).

To help you out you can also define the -DG(TK)_DISABLE_DEPRECATED
macros, but remember to turn them off when releasing the code.
