If you really want to put this in one place and have auto-styled forms, that would be its own class:

class ButtonStyledForm : Form
{
    protected override void OnControlAdded(ControlEventArgs e)
    {
        base.OnControlAdded(e);

        if (e.Control.GetType() == typeof(Button))
        {
            e.Control.MouseEnter += button_MouseEnter;
            e.Control.MouseLeave += button_MouseLeave;
        }
    }    

    protected override void OnControlRemoved(ControlEventArgs e)
    {
        base.OnControlRemoved(e);

        if (e.Control.GetType() == typeof(Button))
        {
            e.Control.MouseEnter -= button_MouseEnter;
            e.Control.MouseLeave -= button_MouseLeave;
        }
    }

    private void button_MouseEnter(object sender, EventArgs e) {
        var c = (Button)sender;
        c.UseVisualStyleBackColor = false;
        c.BackColor = Color.GhostWhite;
    }

    private void button_MouseLeave(object sender, EventArgs e) {
        var c = (Button)sender;
        c.UseVisualStyleBackColor = true;
    }
}

Then inherit from this class instead of Form.
