Notepad is simple to build in Visual Basic, Delphi, heck even assembly because the controls are inherited from Windows[1].

There is no reason to build them for Windows. I just use the ones already available for Windows. I want to build it for Mac so I can get the great simple tools on Windows but on the stability of Mac. For Paint I have resorted to buying a Mac Store app called Paint2 made by some Chinese developer. It is still too complex but is the best I can do now.
