Hello. I am trying to find a way to add translation to certain fields in a front end form similar to backend forms provided by the rainlab.translate plugin. The backend is already translatable and I want to expose part of the fields, with translate capability, of the model to front end user to add/edit model items.

RainLab.Translate is not designed to work in front-end, only backend. I mean you can SHOW translated models in front-end, but not make them editable with the multilingual formwidgets in front-end, unless you code this yourself.

Hello mjauvin, thanks for your reply. My question was not very clear, I am asking for guidelines to code this as you suggested or any other plugin that provides this. Thanks.

You can start by looking at how this is implemented in the Translate plugin.
