virtual keyboard for touchscreen

Hi All,
I’m searching for a virtual keyboard. I’m working in jitter doing an interface for a touchscreen. Inside the interface it is possible to call a web, and I need a virtual keyboard to manage all the information inside the web (registration, comments, etc).
I’m not sure if I have to program the vitual keyboard in jitter or if exist a elegant keyboard for touchscreen that I could download.
thanks a lot for the info
Kind regards,
David
