AC3D[0] is a 3D mesh editor that uses Tcl/Tk for the UI with the core functionality being in C. The "ttk" subset of controls is themable and AC3D has its own theme[1] which, at least to me, it doesn't look that different from the themes of other 3D software. Though it also allows you to edit and create your own themes and personally i made this[2] which i like better (though i think the people who belong in that "majority of users" group you imagine are more likely to elicit that "Ew, yuk." from my theme :-P).
