I love Construct too, but there's always stuff like RPG maker (for traditional RPGs) and the language that uses (Ruby) is honestly not all that difficult to figure out (plus all the open-source codes out there that you can literally copy-paste into your stuff).
If you just want to jump right into it, I'd suggest using programs like that instead, but however, like everyone here has been saying, it CAN be done in Construct, but it's a daunting and difficult task. That's why all of my construct projects have essentially been 2D platformers- because those are, for all intents and purposes, simple.
Simplicity is key- no one knows how to do everything they want with their program of choice when they start out.
like tulamide said, it certainly CAN be done, but if you're just starting out or want the process sped up, there are other options (like RPG toolmaker and RPG maker, etc).
