No worries mate.
I would first get the 2 points from the user
Code:
(setq p1 (getpoint "Select First Point: "))
(setq p2 (getpoint "Select Second Point: "))
Then you would get the distance between the 2 points.
Code:
(setq dist (distance p1 p2))
Then you need this write the distance out to a text file.
Here are some handy resources for text file handling:

That will get you half way the next step would then be to read it from a macro in excel.
Here is a reference which should help:

If you need any more help let me know.
If you want I can give you a few more tips when you get to the VBA macro.
