I need to be able to Edit Subject and Descripton on a custom form but the fields are locked.

I need to be able to edit the subject and description field for one custom form that I am using for Spanish-speaking users.  I also need to be able to add another email button with this form as the only one available.  I can custom code it in but I need some instruction on exactly how to do that because I need to make sure it does not mess up the reports. So to summarise I need two email buttons on one help center brand. One with the Spanish form and one with the English form. And then I need to be able to have the subject and description read in Spanish on the one form.   Is this possible?
