When you say text-based, do you mean where you move around an ASCII-art map like Nethack or ADOM? Or are you thinking of something more like interactive fiction or a MUD, where you get a description of a room and can type (or click) commands?
If the former, I don't know that there's a really trivial way in. There's the
T-engine, which I've heard both good and bad things about. There are tutorials for
making a roguelike in Python and libtcod.
If the latter, Twine is probably the easiest place to start. I know you said you tried it and you're still at a loss, but you might try
this introduction to making a stat-based game. There's also
Inform 7 which has a sort-of-natural-language-like syntax and excellent documentation and lots of examples.
But
anything you do is going to involve some coding (even if it's disguised with a pretty drag-n-drop interface, it's still the same kind of thinking) and quite a bit of work. It's not
that hard but it will take some time and effort. I'd start with Twine, if I were you. It's probably the easiest, you can go a surprisingly long way with it, and what you learn will help you with other systems if and when you decide to move on.
Edit: Seedship is a neat example of what you can do with stats in Twine.
