Beaglebone Black and Keyboard

Hi,
I’m new of Linux and Beaglebone Black.
My Beaglebone Black running with Debian Jessie.
I connected to Beaglebone a 4" LCD touchscreen and i booted the Beaglebone.
It is all ok but i didn’t find a touch keyboard.
Someone can help me to install it?

I should make a GUI applications running in Beaglebone and i need a touch keyboard to imput info.
For building application i saw QT creator do you think is good to work?

Thanks.
