Q:

Display Windows application via SSH X11 on Linux

Is possible to Run SSH server on Windows then make X11 connection forwarding enabled from Linux to this Windows and display Windows application on Linux?

A:

Linux to Windows
An X11 application uses an X Server to display the app's Graphical User Interface (GUI). Microsoft Windows does not come with an X Server out of the box so it can't display them BUT you can install an X Server application that will allow for that and there are free ones you can download and install. 

Windows to Linux
Going the other way, displaying Microsoft Windows applications on Linux, it not possible because Windows uses a different GUI system and as far as I know there is no "server" system that would display a Windows application on a Linux display.
BUT there are ways around that. For Example:

RDP - Fast/Native technology by MS to remotely connect to a windows desktop. It is built in to Windows but needs to be enabled/configured. There are Linux clients.
VNC - Free alternative. You need to install server software on Windows side.
Teamviewer - Commercial app to access Windows desktop. Free for personal use. Has linux client

HTH
