Compucaja Touch Screen Programmable Keyboard (TEP) for Windows

Drag-and-drop simplicity combined with feature flexibility make this a keyboard creator for every level user, but you'll need to know Spanish to read the help file. "Teclado en pantalla" literally means keyboard in screen and describes exactly what this application helps you create. It won't take any time to learn all the commands. Though the occasional error message is in Spanish, the sparse interface and all tool tips are in English.

It's so easy to use that most users won't need the help file. We created a very useful onscreen keyboard in minutes. You merely drag a button onto a blank keyboard and add properties. Presentation, appearance, and data settings are simple to change. It's very easy to set buttons to open programs, launch Web sites, display data, or even open additional keyboards. Almost anything you can program a keyboard to do, you can make this simple application accomplish.

The only missing functionality is assigning sounds when you hover over or press a button, although you can program Teclado en Pantalla to change the color and image of buttons. Keyboards are easy to save and edit later. It's flexible enough for the system administrator to create a kiosk keyboard, and simple enough for computer-novice parents to design a kid-friendly keyboard.
