You can achieve this by using a check box and making its appearance property to button and use it as button.
I think this may help you.

private void checkBox1_CheckedChanged(object sender, EventArgs e)
    {
        if (checkBox1.Checked)
        {
            checkBox1.Text = "Pop";
            MessageBox.Show("Data Pushed into the stack");
        }
        else
        {
            checkBox1.Text = "Push";
            MessageBox.Show("Data Poped from the stack");
        }
    }

This will work as you mentioned.
