may help you . If you followed those steps, then you've built it. I'll copy Section 2.2.10 here.

Modifying an open source python program

it helps some times Because this project uses pyGTK, you can use glade which is a gtk forms designer, but it would probably add an extra layer of complexity that's really not necessary. Since you're already familiar with C#/Java, I'd recommend running through the official Python tutorial. Then I'd take a look at this excellent PyGTK tutorial. If you spend about a day really trying to understand the Python model and the "pythonic" way of doing things, you should then be able to easily modify that program.
While you probably don't need to use and IDE for a project this simple, if you want, you can use Eclipse (which you may be familiar with coming from Java) with PyDev. It allows you to write/debug Python programs inside the what may be the familiar Eclipse IDE.

C# On keypress - exit program

I wish this help you It is an implementation you could use for scenario you described (not tested though):
int exitKeysCount = 0;
private void TrollFrm_KeyDown(object sender, KeyEventArgs e)
{
    if (exitKeysCount == 0 && e.KeyCode == Keys.T)
        exitKeysCount = 1;
    else if (exitKeysCount == 1 && e.KeyCode == Keys.E)
        exitKeysCount = 2;
    else if (exitKeysCount == 2 && e.KeyCode == Keys.S)
        exitKeysCount = 3;
    else if (exitKeysCount == 3 && e.KeyCode == Keys.T)
        this.Close();
    else exitKeysCount = 0;
}

C# Windows Program Exit Request (Detect Application.Exit) No Forms

it fixes the issue See the MSDN documentation for the WM_QUERYENDSESSION and WM_ENDSESSION messages; the parameters of the WM_ENDSESSION message will tell you if your app is exiting normally or because Windows is shutting down. You can handle these messages by overriding the WndProc method in your form, something like:
public partial class MainForm : Form
{
    private const int WM_ENDSESSION = 0x0016;
    private const uint ENDSESSION_CLOSEAPP = 0x1;
    private const uint ENDSESSION_CRITICAL = 0x40000000;
    private const uint ENDSESSION_LOGOFF = 0x80000000;
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == WM_ENDSESSION)
        {
            var sessionEnding = m.WParam.ToInt32() != 0;

            if ((m.LParam.ToInt64() & ENDSESSION_CLOSEAPP) == ENDSESSION_CLOSEAPP)
            {
                // App closing
            }
            if ((m.LParam.ToInt64() & ENDSESSION_CRITICAL) == ENDSESSION_CRITICAL)
            {
                // Critical error
            }
            if ((m.LParam.ToInt64() & ENDSESSION_LOGOFF) == ENDSESSION_LOGOFF)
            {
                // User logging off
            }

            m.Result = IntPtr.Zero;
        }
        else
        {
            base.WndProc(ref m);
        }
    }
}

Modifying exit.c system call code

it should still fix some issue SIGTERM is catchable and in particular can be ignored. You want to send SIGKILL instead. You can't just use the 'kill' system call either. Instead, once you grab the pointer to the child, you send the signal to that. An example how to do it is, well, in the implementation of the kill syscall.
An example code which has to modify children list (add an element) would be clone. An example code which is very likely to traverse the list (and it likely does in your version) would be the wait* family, e.g. waitid.
