You can use Windows GDI[^] to draw lines, curves etc. See Win32 Programming - FunctionX[^] for some useful tutorials.

You can take Diagram Editor[^] as an example and extend its functionality based on the provided base classes

Or DrawCLI sample (in Visual Studio Samples Pack) can be another example as a startup project

But these two projects are based on MFC ,if use of MFC is a problem then you can easily port Diagram Editor to Win32

For hit testing on irregular shapes i would recommend to use of GDI+ instead of GDI
