That's got at least two problems: one, that's not the syntax of CAST,
you need to write CAST(textfield2 AS int4); and two, you can't reference
a SELECT output column from another column like that. You could write
select
to_date(textfield1, 'MM-DD-YYYY') as startDate,
CAST(textfield2 AS int4) as duration,
to_date(textfield1, 'MM-DD-YYYY') + CAST(textfield2 AS int4) as endDate
from whatever ...
