This isn't a stupid question, don't sweat it.
You could an app such as Device Frame Gen or Screen Maker
I don't use either, so I'm unsure if they have your device but they're worth a look.
Personally I use Photoshop and use templates. Simply googling your device and .psd will bring up some.
I used Device Frame Generator
This one is much better and actually works.

You could try Device Frame Generator.
There's a few different apps, but the most popular is probably Device Frame Generator.
