I'm not familiar enough with WPML to know how it says what language the post is. There isn't a built in feature in Gravity Forms for you to select the language because it's not core WordPress functionality so it's not something built into the Post Fields.
If WPML simply stores the language type as a custom field in post meta for that post then it will be as simple as using the Post Custom Field, set the correct custom field name and then configure it as a drop down and set the choices so they use values that are WPML friendly.
You'll need to find out from WPML where and how this data is stored. If it's as post meta, whats the custom field name/key and what is the value that is stored. Is it's the language code, name, what exactly. You'll need those details to be able to implement this.
If you can find out from WPML how the language is associated with the post, we can give you some guidance on how to accomplish this using Gravity Forms.
