Goto System Tab, open ADD TABS.

Add a new TAB and then put in the name of the program.  Full path is not ussually necessary.

OR

Open KONSOLE OR TERMINAL (Install if needed) at # prompt type name of executable (may need full path).
If you get access denied or some such, try typing # su - root
Hit enter for pasword

You have to call something like this:

QString tempfilename = "xxxxx";
 if ( vfork () == 0 ) {
        execl ( tempfilename.latin1(), 0 );
        return;
        }
return;

Please read docu about vfork and execl to get more info
