1.Next thing that i wont to do is to can control the color of a Font (nome of the button) with right mouse click: on first click to make it red and on next to make it black.
 And once the button is red i need to have a option to open a dialog box or a new window with Memo object in which i can write short text. And read it and edit it next time i click on this buton again.

You cannot change the font color of a TButton (Windows owns that property and will not give it up no mater what Delphi says). You can, however, change the color of a TBitBtn.

Use the following code with TBitBtn and you should get the start you need on this.
procedure TForm1.BitBtn1MouseUp(Sender: TObject; Button: TMouseButton;  Shift: TShiftState; X, Y: Integer);
var Btn : TBitBtn;
begin
	if (Button <> mbRight) or (not (Sender is TBitBtn))  then
		exit;
 
	if not (Sender is TBitBtn) then
		exit;
	btn := (Sender As TBitBtn);
	if Btn.Font.Color = clRed then
		Btn.Font.Color := clBlack
	else
		Btn.Font.Color := clRed;
 
end;
 
procedure TForm1.ButtonClick(Sender: TObject);
var Btn : TBitBtn;
begin
	if not (Sender is TBitBtn) then
		exit;
	btn := (Sender As TBitBtn);
	if Btn.Font.Color = clRed then
		begin
		DoOpenMemoDialog(Btn);
		Btn.Font.Color := clBlack;
		end;
end;
 
procedure TForm1.DoOpenMemoDialog(Sender: TObject);
begin
	ShowMessage( TButton(Sender).Caption + ' button was pressed');
end;

Open in new window
