Есть способ намного проще.
Подправить текст самого проекта.

program Project1;
uses
Forms,
Windows,
Unit1 in 'Unit1.pas' {Form1};
{$R *.RES}
var
ExtendedStyle : integer;
begin
Application.Initialize;
ExtendedStyle:=GetWindowLong(application.Handle, GWL_EXSTYLE);
SetWindowLong(Application.Handle, GWL_EXSTYLE,
ExtendedStyle or WS_EX_TOOLWINDOW);
Application.CreateForm(TForm1, Form1);
Application.Run;
end.
