How Do I Force Bulbs Stored in the Fridge Over the Winter?

I never planted my tulips (early bloom and later varieties) or my grape hyacinths this past fall. They are still in my fridge. Does anyone know how to force any of these indoors in a spare front room (north)? Do I need a growing light, as I have only sun in my kitchen which faces south, but has narrow windowsills? I would like flowers for Easter or May, for Mother's Day, if possible. Thanks for any help.
