I want a widget...Plz give attention here

Hi,
I have a forum. I want to offer a new cool application at my forum.

What i want is a widget or something like that. The widget must be such that the registered members of my forum can send sms to any mobile internationally.

Is there any html / php script which can do this ?

Or any paid widget available like that ?

I can pay for such widget too.
PM me if you can help me. Thanks

anyone there who can help me ?

I guess you will need a gateway to be integrated.
You will need to find global gateway provider and use there apis to integrate and send services.
Thanks
