Well, technically yes, you can edit recorded macros; but in actual practice the coding of the recorded steps is so often overly complex and convoluted that the resulting macro is hard to understand and maintain (IMHO). I do use macro recording from time to time as a quick way of seeing how something is done, and then incorporate a much more condensed version of the code into my own macro.
OP, in my experience, there is a trade-off between simple but limited and complex but powerful. It is true the VB of Excel is on the complex side (not so much the programming concepts but the schema for Excel structures), however it does allow you to do almost anything (really anything!) with Excel.
Because Excel has become so dominant, there may already be Excel templates for estimating available on the internet to give you at least a good start. There are also lots of coding samples/examples available by just googling; I frequently find code snippets that I can insert right into my own macros (and even if they are not quite what I need, it is a much quicker way of learning than just reading the manuals).
I'm tempted to tell you to take it on as a challenge because you are not too old and you are bright enough (based on your other postings), but that may be because I actually enjoy coding once I immerse myself in it and that's just weird!
