To do it yourself you'll need to borrow a VCR from somewhere. Then you'll need to install an analogue TV card (which accepts an AV input) or a USB device which imports analogue video to your PC. You'll also need the appropriate lead to connect the VCR output to your chosen device. The TV card (or USB device) will almost certainly come with suitable software to convert the video input to a file which can be stored (and viewed) on your PC. The same software might include a facility to burn the file to DVD, otherwise you'll have to use separate burning software, such as Nero. If your DVD player doesn't recognise file formats such as 'mpeg', you might also require file conversion software to change the video file to 'vob' format (which is what commercial videos use).
If you want me tp provide relevant links, I'll be happy to do so. However, if you've only got a fairly small number of videos to transfer to DVD, it might be far simpler (and not much more expensive) to use a commercial transfer service. Many High Street photo processors can convert VHS video to DVD, but they're usually far from cheap. Google 'transfer videotape dvd' (without the quote marks) for dozens of possible firms, such as this one:
