Gail will be loaded if the whole system's accessibility is enabled. And I am not sure if your application wants to depend on gail. Evolution met the same problem. You can take a look at ea-combo-button.c in Evolution. e-combo-button is based on GtkButton, ea-combo-button is based on gailbutton and Evolution is not depend on gail. Just inherit it run-time.

Don't forget to create the factory. ea-combo-button is a good example I think.
