Doesn't that depend on the screen driver and Windows version that you have available?

Normally is a hardware question...
in the games where you change the brightness it  is changed in the image shown, not in the hardware settings. So you could change your program's colours to make it appear brighter or darker.
The same is valid for the brightness setting of some video drivers (it is only apparent)

I have an application written in Delphi, and I want to add a dimmer bar, so that the brightness of all the forms and components on them could be changed.

mmh!
you could change at runtime the color property of your form and components, and
use RGB( ) function to dimmer the brightness, but not every control support the color property, so you have to choose the right components to use.
 
var
  brightness:Integer;
begin
  brightness:=(whatyouwant in 0..255)
  form.color:=rgb(Brightness,Brightness,Brightness);
  //and the same for all your components
