This one is easy, let's skip that for now.

- In the background I need to implement a function which will be executing the process createds by the users (with time slice, changes of process, etc.)...
You will need QProcess for this.

So[2] I my mind (tired mind hehe), I only think in threads to make this program work simultaneos (user view, lists` animation and the mainfunctions)... some guys talk me about timers but I still not see how It could help me...
You can use timers for animation so that you have constant frame rates but apart from that you probably won't need neither timers nor threads.

So[3], the first step is, I really need use the QThreads?
No, you don't. Unless you will be using some solutions where you can't avoid blocking the main thread.

Ah talking about the animation, what`s the way to make something like:
char c;
while(c<`z`)
{
ui->line_edit->setText(c);
c++;
}
It`s works, but not like an animation hehe i mean how to show the `counter couting` to the user?
How about using QProgressBar or QProgressDialog?
