It is complicated, and can be expensive, but it's something you can definitely do. I will outline the steps for you.
Those camcorder tapes are analog, and your computer is digital, so the very first thing you need to do is to convert the tapes to digital format. Converting analog video to digital format is known as capturing the video, and in order to capture video you'll need a capture device.
If you're lucky, your camcorder may have a capture device built in, or your VHS player may have one. If not, you'll have to purchase a capture device, like this Dazzle device from Pinnacle Systems. There are others like it; I only mention the Dazzle because it's what I used to capture my wedding video.
The great thing about a capture device is that everything you need is included in the box: Aside from the capture device itself, you'll get cables, software and instructions.
Capturing video is a very processor-intensive activity. That's a fancy way of saying that you'll need a powerful processor (aka CPU) inside your computer to get the job done, and the more powerful, the better. You need to give that processor every opportunity to succeed - that means don't do anything else on your computer while you're capturing video. I mean, nothing else. Disconnect your computer from the internet, turn off (or uninstall) your antivirus program and don't do anything else on the computer. You want your computer to be like the Autobahn with no other cars on the road.
You'll also have plenty of decisions to make, a lot of technical decisions, but don't let that throw you. Just take your time and do the reading. You need to decide how you will capture the video (interlaced or progressive) and what technique you want to use - the technical term is codecs - because different techniques get you different image quality. You also have to decide how to capture the sound, and here again different techniques get you different sound quality.
Once you've captured the video and audio, it's now inside your computer in digital format. But you can't declare victory yet. Now you need to decide how to take the imported video and audio and turn it into a finished product. You can do it simply or go all-out Hollywood. Up to you. The software included with the capture device may be sufficient, or you may want to purchase additional software. 'Rendering' your video (i.e., turning it into a final product) is also very processor-intensive.
I don't mean to put you off with this description of what you're getting yourself into. It's nothing you can't learn - heck, I learned - and there are many websites and forums that will help you. (Not this place.) You can do this.
