It depends on whether you have the right tools, know how to do it, and know the special secrets. There is no reason you cannot do this yourself, but not until I share my wondrous wisdom with you. Where I would start is by visiting a community college's library where they have an automotive program, or visit one of the instructors. You are looking for an "Automotive Brake System" text book. You do not have to memorize the whole book. Just read through the section about performing a typical brake job. When I was teaching, I always had out-dated, yet current books to give away.
The manufacturer's service manual is also a good reference for how to get the old pads out and put the new ones in, but they still do not cover the things you can accidentally do to cause squeals and vibrations or the things professionals do to prevent those things.
I cannot tell you the type or size of wrench / socket you will need to remove the calipers. If you have access to a tool box full of typical sets, you will be able to find the right size through trial and error. You will also need a fairly large flat file, a small bottle of special high-temperature brake grease. "Rusty Lube" was one trade name. Any auto parts store will have this. It is not regular lubricating grease. You do not want any petroleum-based product like axle grease, engine oil, or power steering fluid anywhere near the brake fluid.
Let me know when you have the new pads and tools and are ready to get started. I will start typing my list of precautions. Be aware too that you must never ever push the brake pedal more than half way to the floor. This is even more important on GM front-wheel-drive cars because you can cause a big problem of only one front brake working. I will cover that later.
