I started making music limited to just pre-made samples and loops. It wasn't ideal, but I think it's a big part of how I started learning to make things so quickly, and I still use them all the time. Starting from scratch can be demotivating because everything--drum programming, bass, chords, lead melodies--has its own challenges to tackle. Loops can be great for giving you something to base an idea around or quickly adding a new element to play with.
With that, I strongly recommend Music Radar's growing collection of free loops and samples--now up to over 70,000 WAV files.
Since instruments and DAWs have already been heavily discussed, I thought I'd mention this other angle. There are an overwhelming amount of products on sale for music-making. Other than my main program Ableton Live, there is no software or hardware I have ever bought that made me think "now this, this solves all my problems". Keep it in mind when being sold on new products that if you don't already know exactly what they'll add to your setup and how you are going to use them, they probably aren't worth it yet.
YouTube is an endless, excellent resource for tutorials. For whatever DAW you choose, there is bound to be a video series explaining its interface and functions and making this all a little less overwhelming (I learn best by being shown)
Andrew Huang has a gleeful think-outside-the-box approach to music production, though the content assumes some knowledge.
Reverb has a great series with a walkthrough of how famous synth sounds are made that may help with synth fundamentals.
But there is SO MUCH content on YouTube that you should assume you will get some result from typing just about any term or query in.
