All you have to do is change the fixed coordinates in your DrawRectangle to variables, and alter the variables.:

private int rectLeft = 20;
private int rectTop = 30;

        protected override void OnPaint(PaintEventArgs paintEvent)
        {
            Graphics g = paintEvent.Graphics;
            Pen pen = new Pen(Color.AliceBlue);
            g.DrawRectangle(pen, rectLeft, rectTop, 450, 280);
            pen.Dispose();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
        rectLeft += 20;
        rectTop += 10;
        Invalidate();
        }

(I cut your code down a little to make it clearer)

Note that you are responsible for disposing any pens, brushes, etc. you create! Failure to do so will result in odd seeming problems...
