I would think you should be able to use QProcess to do it. You can access the input and output channels of the process. Start dmidecode with a QProcess. Check the program output for whether it asks the password, and then ask the same from the user in a dialog in Qt.. then send that password back on the input channel.

From Documentation of QProcess:

bq. QProcess allows you to treat a process as a sequential I/O device. You can write to and read from the process just as you would access a network connection using QTcpSocket. You can then write to the process's standard input by calling write(), and read the standard output by calling read(), readLine(), and getChar().
