Gtk is *LGPL*-2, so you can't make it GPL-2 (unless you convince all contributors, including aliens and dead).
Yes, you can. Quoth the LGPLv2.1:"You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. [...] (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.)"
Personally I think this clause is kinda ridiculous, but it's there, nonetheless. Any LGPLv#-covered program can be relicensed as a GPLv#-or-later program as well. Interestingly, my reading of this shows that, even if you license under "LGPLv2.1-only", someone can relicense as GPLv2-or-later, or GPLv3-or-later, or even GPLv3-only.
