I gave this list in one of my OSCON talks, I think it is still mostly 
accurate:

1. Derive from wx.PyControl. This enables reflection of some pertinent
C++ virtual methods to Python methods in the derived class.

2. Call SetInitialSize from the __init__ method, passing the size
passed to __init__. This helps set things up properly for sizers, and
also sets the size of the control appropriately (using either the size 
given or the best size.)

3. Call InheritAttributes from the __init__ method. If the parent has
non-standard font or colors then it will set them for your control.

4. Implement a DoGetBestSize method, returning the wx.Size that would
best fit your control based on current font, label or other content, etc.

5. Implement an AcceptsFocus method, returning True if the control is
meant to receive the keyboard focus.
