Short answer: yes, you just have to share any modifications you make to
GTK+ (probably none). See
http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License for
details.

No, but I would ask you to seriously consider an open source license.
For me, the perceived advantages of proprietary software seem to be
outweighed by the extra attention/help you will receive with open
software.  Although anyone can get the app for free, you are the expert
that can help with support/customization, and that knowledge/experience
is the truly valuable part.

dbus is dual licensed, GPL (your program must be open), or
APL(http://en.wikipedia.org/wiki/Academic_Free_License) which would be
how you had to license it for it to not be open.

Yes, as long as the GTK+ libraries are installed (almost a certainty on
nearly every distro).
