It's not hard to dynamically create a form, although you need something to determine what it should contain for each request. The three-argument form of (Python) type can be used. For example,

fields = {
  'foo': forms.CharField( max_len=80 )
  'bar': forms.IntegerField() 
}
MyForm = type( 'MyForm', (forms.Form, ), fields)

...
form = MyForm()

which is the same as

class MyForm( forms.Form):
    foo = forms.CharField( max_len=80 )
    bar = forms.IntegerField() 

...
form = MyForm()

except that you can construct the contents of fields dynamically, using some runtime entity to decide what fields with what names and of what type should be in the form.
