Yeah of course it is possible!
I assume 2K is ntfs? right so open your /etc/fstab as root (log in as root in a shell and type kwrite /etc/fstab) and add this into it:
/dev/hda1 /mnt/windows ntfs ro,umask=0222 0 0
where hda1 is the name of the partition or drive your 2K install is on and /mnt/windows is where you will be the folder you are able to access your windows install if you'd prefer a folder on your desktop then change it to /home/yournamehere/Desktop
Make sure you make the directory, so if you want it on your desktop in a directory called windows do:
Right that takes care of it appearing everytime you boot but to get it to appear and be mounted the first time type:
that should be it, if you run in to trouble with Slack not mounting it try this:
mount -t ntfs /dev/hda1
As for your second question, well this ain't so easy, ability to write to ntfs is very experimental and not to be relied on, if you have your 2K install on a FAT partition then that shouldn't be a problem just copy stuff across but if it's ntfs then I can't help, you can of course still transfer stuff to a floppy or burn to a CDROM from linux
Oh, and one last note, I assume that you've got ntfs support compiled into your kernel...
