Default Help with C++ & wxWidgets

Well, I am new to these forums, and am looking for some help. I am trying to make a minor program with wxWidgets and C++. Yet, I do not know where to begin. Or, even if I am heading in the right direction...

Maybe if I elaborate on what I am trying to do, you guys can point me in the correct direction...

What I would like in my program is:

You select a number between 2-48, when you select the amount, and compile it. After you compile the numbers, out pops the text.

What it is for, is an engine in a game I am "trying" to make. It involves a lot of switches that need to be randomized. But, I think it would be faster if I was able to make a program that outputs the text, so you can just copy+paste it.

If I am still unclear, please, tell me. I will try and elaborate more to help you, help me.

By the way, here is the code to wxWidget's basic GUI.

Code:

// for all others, include the necessary headers (this file is usually all you
// need because it includes almost all "standard" wxWindows headers)

    // initialization (doing it here and not in the ctor allows to have an error
    // return: if OnInit() returns false, the application terminates)
    virtual bool OnInit();
};

// Define a new frame type: this is going to be our main frame
class MyFrame : public wxFrame
{
public:

    MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size,
            long style = wxDEFAULT_FRAME_STYLE);

    EVT_MENU(Minimal_Quit,  MyFrame::OnQuit)

// the application object during program execution (it's better than using a
