For a form with a <select>, use ChoiceField:
>>> class FrameworkForm(Form):
... name = CharField()
... language = ChoiceField(choices=[('P', 'Python'), ('J', 'Java')])
>>> f = FrameworkForm()
>>> print f['language']
<select name="language">

MultipleChoiceField is a special case, as its data is required to be a list:

... name = CharField()
