input fields - How should I implement Language selection in a CMS?

One of my client must be able to post News to both french and english language on his website. I would like to know how I should design the CMS to be the most convenient for the admin as possible.

Below is captures of what I thought would solve the problem but I doubt it's the best way to do it as I am no UX expert.

I would like your advices on that if possible.

Answer

Vertical workflow is more natural than horizontal unless the user is comparing content side-by-side. Moreover, horizontal arrangement requires users to have very wide monitors to work comfortably. Finally, there's no need to force users into a particular sequence of languages - let them decide what version is going to be posted first.

Thus, the mock-up will look like this:

Note that the radio buttons should be listed vertically despite the available space in the line (unless you have multiple columns of languages) and that the "Add translation" button should be placed closer to the editor than to the publishing controls.

Clicking "Add translation" (or whatever you want to call it) should duplicate the language selector and the editor controls right above the button so that the publishing controls stay separate from the editor.
