choice of language/technology for extensions

I wonder if anyone here can help me, I am currently bewildered by the array of options for extending arcmap.

I need to make a custom edit tool that selects/modifies polyline feature classes.  It should work in both arcmap 9.3 and 10 (so I guess that precludes using add-ins if these are new in 10?)

It seems like using arcobjects COM extensibility is the way forward (or am I wrong...) though I'm not clear whether this is best done with C++ or C++ .NET, or even VB.  I don't have an EDN license, does that make a difference to the options available to me?

Many thanks, C.
