I see. I would think Ch binding to GTK+ will promote
the use of open language C/C++ and GTK+. After all, to have
a cross platform GUI applications without compilation are appealing to
many
C/C++ users. I believe our C/C++ interpreter is the only one 
that can run the original GTK+ sample code in C interpretively
without any modification of the source code. In many aspects, it is
not just a binding. It is a seamless integration and makes GTK+
interpretive.
We intend to make Ch 3.5 for Linux free for both personal and
commercial use. Ch GTK+ will make GTK+ readily applicable for
script computing.

The license you read is about our proprietary part for Ch integration. 

You may check the license online at
http://www.softintegration.com/download/register/license/license4ChGTK.html

If you read more, you will find the section 
" The software may contain open source
components identified and governed by licenses in the
 directory CHHOME/toolkit/license where CHHOME is the home directory in
which Ch will be installed. Those open source
 components are governed by their licenses in the above directories."

This license is located at CHHOME/toolkit/license/license_GTK.
CHHOME/toolkit/license/other/README_GTK contains:

"GTK+ header files in ../include/gdk ../include/glib ../include/glib.h
as well as original GTK libraries without any modification located in
CHHOME/extern/lib in Unix or CHHOME/toolkit/bin in Windows
are copyrighted under the GNU LGPL in 
license_COPYING --- GNU LESSER GENERAL PUBLIC LICENSE"

You are welcome to have a try and feel free to let me know if there is
any
comments and suggestsion related to our license or use.

It is a great idea. The same GTK+ header files can be used in our C
interpreter without any modification. Can you please let me know to whom
we should submit the patches?

Sure.
