I think many people share this view.

 - you don't want to build your towers of complexity in C++ -- you
want them in Scheme (where hopefully the towers will be simpler)
 - there are simpler libraries you can interface to that do most of
the work in a cross platform manner

I base this reasoning on the 'Shoes' project in Ruby:


There is relatively little code behind it (a few thousand lines of C
IIRC).  It relies on Pango and Cairo for most of the rendering -- with
some OS specific code for widget controls.  Pango and Cairo are C
libraries, so fairly easy to bind (no templates, no name mangling,
memory handling is explicit).  The OS libraries likewise.
