Android based software

We need a menu application that will start up with our device, and allow the standard user in our system to work with the shortcuts to the applications that are in the menu only, without an option to leave this menu.(application will be installed on the device) the Admin will select different shortcuts to add to this menu. this is not a cell phone device rather than an embedded board. the end user will not have access to the computer itself rather just to the monitor and mouse. the intention of this app is to make sure the user uses only allowed applications and not enter the computer settings. As we dont have something written down, please write some Q for us to replay. the device is not a cell phone only an embedded board ,and the user has only a touch screen to work it the standard 3 button on the low part of the screen are disabled, and do not exist. the os is 4.0.4 please let me know what else you need for a quote.
