Integrate "Linux Binary Library" into program

Question

Hello Everyone,
I am trying to create diferent kind of application, like a DVD burner, ArchLinux usb Creator, WBFS Manager (I know that they exist a lot out there but I want to create mine in qt) etc..  and I know how to do this by using the command line, but I want to integrate those features with a Gui in QT (or another language like java, but I still prefer QT for this).
I just don't understand how this can be made, how can I import the function of "dd" for example to my program ? Some library have a especific api for python, qt etc... but not all. I have thought about using Qt to launch terminal command like if I was in the terminal, but there will be no interaction with the gui I think.
And for the "Command Visual Commands" ? Like for example, with wit (Wiimms ISO Tools),
I can do this : "wwt LIST /dev/sdf2" and this game me the fallowing output from the terminal :
ID6     4/214 discs (11 GiB)
RMCE01  MarioKartWii
SP7PAF  PAC-MAN PARTY
SOUP01  The Legend of Zelda Skyward Sword
SLVP41  We Dare
Total: 4/214 discs, 11224 MiB ~ 11 GiB used, 91174 MiB ~ 89 GiB free.
How could I organize those information ?... Maybe if the software propose to separate them and Then it is my work to just organize them, but if the command line software don't propose how can I do so ?
Sorry for so many questions, and my horrible english.
PS : Don't be worried about posting "complicating" language terms of Linux functions, I have "a lot of experience" with those two and if I don't understand something I will just move my ass and search before asking ^^
Thanks in Advance,
Luis Da Costa.

I'm thinking QString and/or QRegExp.
I know this isn't a detailed reply, but I'm in a bit of a daze right now (past midnight here), plus I figure you just want hints, not your hand held.
