Mobile friendly widgets and plugins

Hi All,
I know there are mobile sites and ways to make WordPress mobile. I even no about the redirects and such that recognize mobile and send them to those sites.
I'm hoping to find something a little more refined then that.
What about widgets that only show in mobile devices es.
Like if statement that say if mobile?

Anyways, what I need to do now is add three buttons.
Call now, email now and sms or text now.
I want them to use the mobile devices resources to carry out the functions.
Is there such a plugins, widget or short code that will add features such as these?
My guess is there is simple html to do most of it, but I am not a coder yet and really need some help to make this happen.

Any ideas?

Thanks for the time
Richard
