create a webform node with multi lingual language
You can use Internationalization module to achieve this functionality.


  This is a collection of modules to extend Drupal core multilingual
  capabilities and be able to build real life multilingual sites. Some
  features:
  
  
  Taxonomy translation (both, per language terms and translatable    terms) Multilingual variables
  Multilingual blocks (control visibility per language and translate    title and content)
  Language selection (when you switch the site language you'll see only    the content for that language)
  


Edit:

You need to set up translate of each node. If you create node/2 as defualt language French, then you edit the node and click on translate tab in top of page and set up translate node in spanish language.

If you view node/2 and select spanish language, then it will display the trasnlated node of node/2 in spanish language.
