On UN*X, it's main(), in gtk/main.c, as Jaap Keuter noted.

On Windows, it's WinMain(), but Ethereal's WinMain() just sets an internal
flag and calls main(), so the code doesn't have to differ very much
between UN*X and Windows.

"Like Win32" in what sense?

GTK+ doesn't load the program; the program is linked with GTK+, so, when
the OS starts the program, the GTK+ libraries are loaded with it.  (The
Win32 GUI libraries work the same way.)

As for how it responds to window events, etc., you should probably ask
that question on the gtk-list mailing list:

    http://www.gtk.org/mailinglists.html

as it's not an Ethereal question (and does not have a very simple answer).

The command-line version is called Tethereal, and the main entry point is
main() in tethereal.c.
