In GTK apps each standard text widget has its own context that is
internal to the widget. So yes, you can have multiple contexts.

I suggest you look at the source code of GTK, specifically at the part
of GtkEntry that deals with the context creation and use. While you
could associate a context with each window, it probably makes more sense
to keep the contexts internal to your custom widgets. The context also
keeps some limited state, so it's best to have one context per instance
of your forms.
