You can build Denemo against Gtk2 but there are some features that are
not so good. IIRC Gtk3 has switched to using cascading style sheets (or
some such terminology) where you can specify the style of things at an
extremely granular level - Denemo is exploiting this internally, e.g.
to paint the background of the frames differently for the different
types of Denemo Directive in the Score/Movement/Staff/etc editors.
Ideally this would be done by providing a style sheet with Denemo that
the user could then adjust, but, as I say, I haven't delved so deeply
into how that would work.
I think the installed Gtk3 libraries that you have will include a
variety of styles and something to specify the default, so, short of
finding a Gtk3 theme chooser program you could directly alter that
default (probably by putting the choice in some .config file in your
home directory).
