Is it possible to have an array of components (for example TEdit) in a frame? If 
so, must I create them at runtime?

Answer:

You can create the components at design time, as usual. But you have to set up the 
array with the component references at run-time. This is quite painless if you use 
the default naming for the components the IDE produces, or something equivalent, 
with a running number at the names end:

1   { ... }
2   private
3   Edits: array[1..10] of TEdit;
4   public
5   
6   constructor Create(aOwner: TComponent); override;
7   { ...  }
8   
9   constructor TFrameX.Create(aOwner: TComponent);
10  var
11    i: Integer;
12    edt: TComponent;
13  begin
14    inherited;
15    for i := Low(Edits) to High(Edits) do
16    begin
17      edt := FindComponent('edit' + IntToStr(i));
18      Assert(Assigned(edt), 'Edit' + IntToStr(i) + ' not found!');
19      Edits[i] := edt as TEdit;
20    end;
21  end;
