Here is shorter code to add a custom page to Inno Setup installer with an Input Field:

var
  CustomQueryPage: TInputQueryWizardPage;

procedure AddCustomQueryPage();
begin
  CustomQueryPage := CreateInputQueryPage(
    wpWelcome,
    'Custom message',
    'Custom description',
    'Custom instructions');

  { Add items (False means it's not a password edit) }
  CustomQueryPage.Add('Custom Field:', False);
end;

procedure InitializeWizard();
begin
  AddCustomQueryPage();
end;

procedure CurStepChanged(CurStep: TSetupStep);
begin
  if CurStep = ssPostInstall then
  begin
    { Read custom value }
    MsgBox('Custom Value = ' + CustomQueryPage.Values[0], mbInformation, MB_OK);
  end;
end;
