Sorry, I was in pattern matching mode, and assumed that you guys were
using Python.

You are using a dialog to interact with the user, aren't you. That dialog
knows which WorkbookControlGUI it belongs to. Dialogs typically wrap
their state in a struct which is passed as the last parameter to a
callback. You should make sure that your WorkbookControlGUI can be
reached in this way.

Going from workbook would sort of work, but breaks Gnumeric's
architecture. There are many views for each workbook, and you shouldn't
just choose one at random. 

Show me some code if this info is too general to be helpful.
