I might encourage you to think about using the architecture I describe 
here: http://blog.ianbicking.org/a-theory-on-form-toolkits.html -- 
either using FormEncode, pieces, or just the general idea.  E.g., I 
think something like FormEncode's htmlfill that used stan could be 
useful, and FormEncode doesn't currently include anything very good for 
actual HTML generation.

Anyway, I think keeping the parts separate (blank HTML form generation, 
validation, final form rendering) is really important to making a usable 
system; without it people just keep creating form toolkits that they 
later come to hate because the abstraction boundaries don't fit the 
actual development process.
