You can go ahead and put callbacks in any area of your app, or even
in a shared lib that your app is linking against - note you might
find it tedious to seperate callback code by widget, note2 since you
are working with a dynamic UI you probably want to abstract the GUI
from your callback code.

In an ideal world (well, my ideal and some folks too), you can have
a GtkAction of all kinds of types to connect signals to, regardless
of what button you decided to put in what window or whatnot, your
code should only be concerned that the user somehow said "Play!"
or, "crank up the volume a notch", you can then go ahead and completely
change your GUI and since you have the same actions with the same
callbacks attached, it will "just work" (ofcourse the action stuff
is sadly currenlty limited to menuitems and toolbars, but this idea
should help shed some light on how you might want to design your GUI
code).

Well something is askew here, care to post the output of "make" in your
project so I can verify you put --export-dynamic in the correct linker stage ?

You should also try an "nm myapp" and see if your callback symbols are
indeed exposed in the text segment of your binary (i.e. marked with "T").
