I don't know anything about sql-alchemy, from what you write my first
idea too was to subclass StringVar and add a datatype attribute to the
new SqlVariable class and let get() and set() handle the conversions
according to self.datatype. If you have only the five mentioned datatypes
I think this shouldn't be too hard and might prove quite handy then.
For the date and time datatypes maybe you could borrow some code from the
Pmw.EntryField validation mechanisms.
