Don't think I'm an expert, I'm just starting with Glade-3, and until now,
not entirely enjoying it yet, ;=)

Well, assigning the ListStore to the ComboBox is easy with

gtk_combo_box_set_model

Assuming you made a one column ListStore, that's all there is to it.

Then afterward, you can use the selection of the model
(gtk_tree_model_get_selection) to get at the item selected.

It's not as easy as the ComboBoxText, but it does give you a better
control on what happening.
