I wanted to write a program that has no window but may show messages to

I have lots of such programs written with Virtual Pascal but I am
struggling
to do the same with Free Pascal/Lazarus.
A simple test program would look like this:
--------------------------------
program Test;
{$mode objfpc}{$H+}
uses Interfaces,Forms,Windows,SysUtils,Dialogs;
{$R *.res}
begin
ShowMessage('TEST');
end.
--------------------------------
Creating a console program is not an option because it will create a
console window which I don't need.
Anybody who knows why it is like that?
A GUI program requires a "main window" since that is the avenue for user
interaction. You can hide that window (not "ignore" it) as in the
following program, which compiles and runs. However, I can't myself see
the use of such truncated GUI functionality. Once the main form is
hidden, I see no way for the user ever to get back to it.
program Project1;
{$mode objfpc}{$H+}
uses
Interfaces, Forms, Unit1, Dialogs;
{$R *.res}
begin
Application.Initialize;
Application.CreateForm(TForm1, Form1);
Form1.Hide;
ShowMessage('TEST');
Form1.Close;
Application.Run;
end.
