Which language?  Have you ever done bindings in that language before?  Usually you would wrap a library by making equivalent API calls in that language and marshaling API parameters and results using the glue C/C++ libraries that the language provides for creating modules.  More complex libraries usually have some sort of automation for this and some languages have generic automated 
binding tools like SWiG.  With the advent of GObject-Introspection you can now write a minimal interface module that reads in the gir files and routes and marshals method calls based on the gir data structure.  PyGObject is a poor library to look at because it does not yet use GObject-Introspect and does the wrapping with its own targeted tool.  It is better to look at the Gjs or Seed javascript bindings.  Every language is going to be different as they all have their own API for creating C extension modules so again, you need to know how to wrap a simple library in your language before tackling GTK+.
