Probably overkill, but by far the easier way to create this would be getting Delphi Starter edition (free for new users) and just create a new project, then drop your buttons and components on the new form, then press F9.
In order to get a standard Windows dialog, you can use some code:
procedure TForm1.FormCreate(Sender: TObject);
begin
MessageDlg('Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed ' +
'do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ' +
'ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut ' +
'aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit ' +
'in voluptate velit esse cillum dolore eu fugiat nulla pariatur. ' +
'Excepteur sint occaecat cupidatat non proident, sunt in culpa qui ' +
'officia deserunt mollit anim id est laborum.',

end;
