Change label according to thread culture. Need Help. Thank You.

[Shapper]

Hello,

I have a multilanguage web site.
In a contact form I have a few labels. Something like:

Subject:
<Input Box>

CODE:
<label for="subject">Subject:<input type="text"
id="sbj"></input></label>

What is the best way to change the label "Subject" according to the
value in my thread.culture value?

How should I do this?

Thank You,
Miguel
