One of the strongest arguments in support for using WTL over MFC was the fact that executable of WTL will be around 4x smaller in size than statically linked MFC Application.
 
Now, given the fact that we are living in 2015 now, does it really matter? If your program is 8MB or 2MB?

I wonder if it’s necessary to insert destructors for the classes of the project.

But what’s the situation for classes that I have inserted in the software?

I never put destructor for these objects (dialogs, strings, bitmap, controls, custom objects…)

class YourClass
{
   ~YourClass (){/* no need to delete m_Bitmap */};
   CBitmap m_Bitmap;
};

class YourClass
{
   ~YourClass () {delete m_Bitmap;};
   CBitmap* m_Bitmap;
