I know Construct is a game maker engine, but can this be done? Can I create something like notepad, wordpad, Word, etc using construct? I'm a writer and I'm entertaining the idea of creating my own personalized writing app.

I wouldn't recommend this, it will be really difficult. Construct is not the right tool for this task.
I've done some really complicated text processing with C3, and I know you could use base64 to make your own file format that stores custom formatting and such along with all your text, but I don't think I'd ever want to make a full blown word processor purely to write.
