I added the website translator gadget to my blog.........

..........check it out.
You can find out how to install it on your own website here and it's very easy.
So now, with this included in my blog's HTML, anybody that opens my blog using a browser whose preferred language is not English should see a Translate button at the top of the page as you can see in the screenshot.
I've tried it using Portuguese (BR) and it seems to work pretty well.
