Answer 1

If I get it correctly you want to add a button to the form, from code and not with the designer.

It's not that hard. Just add an eventhandler for the load event of your form. Instantiate a button, set some properties of that button and add it to the control collection of the form.

private void Form1_Load(object sender, EventArgs e)
{
    //instantiate new Button
    Button btnNew = new Button();

    //edit some properties.. size, location, text
    btnNew.Text = "Hello world";
    btnNew.Size = new Size(100, 20);
    btnNew.Location = new Point(50, 70);

    //add an event handler for the click event
    btnNew.Click += btnNewClick;

    //add the button to the controls
    this.Controls.Add(btnNew);
}

private void btnNewClick(object sender, EventArgs e)
{
    //method for the click event.
    MessageBox.Show("You clicked the button");
}
