Touch Screen Chats?

I was wondering if anyone has seen or developed any plug ins or builds of spark that have a built in keyboard for using the chat box with a touch screen? Because I would love to be able to a single window with a keyboard attached for doing chats. I use a windows PC touch screen with a particular programs for logging some information and do not have the availability to use an actual keyboard. Plus the program is forced on top so it is excessively hard to try and do a different virtual keyboard that is not directly attached to the chat window. That is due to not having access to my windows taskbar and such. So if anyone can help point me in the right direction that would be awesome.
