Wordpress - edit WPUF plugin to work with WPML

We are using the plugin http://wordpress.org/plugins/wp-user-frontend/ to create forms that’s users fill out to upload new posts to the database.
We are also using WPML to translate the website into English and Spanish.
Using WPUF we need to be able to stay in one language and be able to upload posts into English and Spanish.
So if we are in the English side of the website, we need to upload a post into English and then staying in the English side of the site, upload a post to the Spanish side.

If we do this from the Wordpress admin it is working, WPML lets us create posts in English and Spanish and they are saved correctly. - So we need to intergrate this into the WPUF plugin so from a created form we can select the language that is uses and the it will be shown in English or in Spanish.

We have found these two post which are solutions to what we need, but we dont know how to intergrate this code and how get it working:

And

We need someone that knows wordpress VERY well, WPML and WPUF.
