I believe there's a combination of XMing and Putty that will do this

http://www.straightrunning.com/xmingnotes/

However if you simply run XMing it will probably just give you a window 
representing your entire Raspbian (etc.) desktop, which won't help C&P. 
Also I don't know whether the Display Manager supplied with Raspbian 
supports remote sessions, and I'd not suggest fiddling with it.

Strictly, server since it provides graphical services to the actual 
program. This is non-intuitive and most people will look uncomfortable 
if you ask them to justify it :-)

Well stop fscking around with Windows and use your Ubuntu machine as the 
controlling desktop. As I've said, to the extent that my patience is 
exhausted, the standard OpenSSH supplied with both Debian/Ubuntu and 
Raspbian allows you to tunnel X, you'll probably need to change one 
setting on your desktop system (in /etc/ssh/ssh_config):

Host *
#   ForwardAgent no
    ForwardX11 yes
#   ForwardX11Trusted yes

after which the SSH client (i.e. your desktop system) will tell the SSH 
server (Raspbian) that it's prepared to tunnel X traffic, so if you use 
a shell over SSH to start lazarus the GUI will appear on your desktop 
system.

There's advantages and disadvantages to this that I've described more 
than once, so I'm afraid that I'm not going to do so again.

Now for heavens sake man, if there's something about this that you don't 
understand then /ask/ rather than just ignoring it.
