Excellent! That link pointed me in the right direction. This seems to work:

        Form f = new Form1();
        f.FormBorderStyle = FormBorderStyle.FixedToolWindow;
        f.ShowInTaskbar = false;
        f.StartPosition = FormStartPosition.Manual;
        f.Location = new System.Drawing.Point(-2000, -2000);
        f.Size = new System.Drawing.Size(1, 1);
        Application.Run(f);

To keep it from showing up in Alt-Tab, you need it to be a tool window. Unfortunately, this prevents it from starting minimized. But setting the start position to Manual and positioning it offscreen does the trick!
