Webform Auto Field

This module adds a textarea to the Webform creation form to enter a list of field titles. It also adds an additional field to select textfield or textarea generation. This list is used to automatically generate fields for each one of the items in the list. This saves you a lot of time if you need to generate multiple fields of a particular type for a long form.
Here's a short video demonstration:

Drupal 7 Version

The module changes slightly in the D7 version. After you have installed the module, you will find a link labeled "Bulk generate form components" under the Webform tab. There you will find the form to pick the type of components and enter the Names (labels).
This version also adds the feature of optionally being able to make all of the form components generated mandatory.
