What you are asking for is an entire game, on an ancient version of UE. Sorry to be negative but you should ask specific questions when you have tried to implement a certain mechanic yourself and run into a problem you can not solve. There are plenty tutorials online.
GUI - as an example - I don’t think there is UMG in 4.0.2 (someone corrects me please) - so you wouldn’t be able to make an interface. You’d need to rely on something like HUD which will get you nowhere.
Anyhow, if you’re serious about game making on UE4, you’ll need a better machine sooner rather than later. It’s fine for learning or making the most basic stuff, though. Assuming that’s the laptop with the discrete HD 6470M rather than HD3000.
Lets very optimistically assume OP is running the most potent option:
Intel Core i7-2820QM Processor (2.30 GHz, 8MB L3 cache, 4 cores/8 threads, 45 W) Up to 3.40 GHz[…]
Start compiling shaders and that laptop will melt into the table after the 1st hour. I still think they can learn the fundamentals, but completing anything larger than tiny will get rather frustrating.
If they’re sitting on 2c/4t instead, working with the editor will be a nasty experience. Also, mechanical drive + 8GB of RAM is a nightmarish combo…
