Well, no.  It's true you can't put a filesystem on a mounted partition, but
you neither mount the extended partition nor the new partition.

Personally, I wouldn't even bother resizing anything, but create a Logical
Volume under LVM, but let's not go there yet...

Boot from a LiveCD.  From there you can use gparted to extend the size of
the Extended partition to include the remainder of the disk.  Then create a
new logical partition in the unused space.  To this point, you have not
even touched a live filesystem.

The last step is to put a filesystem on the new partition - you should be
able to do that either with gparted or after rebooting - and create a mount
point for it.
