The user would give out the number of buttons.

void CreateButtons(int num)
{
    Button[] button = new Button[num];
    for (int i = 0; i < num; i++)
    {
        // Anything that cocoonwls said.
        button[i].Click += new EventHandler(Buttons_Click);
        this.Controls.Add(button[i]);

Every button should have its own working onclick code

void Buttons_Click (object sender, EventArgs e)
{
    Button b = sender as Button;
    switch (b.Name)
    {
        // Code for events
    }
}

if(e.KeyChar==37)<br />
                txtStatus.Text = "You've pressed the left arrow key.";<br />
            if(e.KeyChar==38)<br />
                txtStatus.Text = "You've pressed the up arrow key.";<br />
            if(e.KeyChar==39)<br />
                txtStatus.Text = "You've pressed the right arrow key.";
