Can I install Windows 7 on iPad 2? I want to use Windows 7 on my iPad 2. Could this be done in a general case? 

If it can not be installed, please let me know how I might get as close to having windows running on the iPad as I can get.
It cannot be installed on the iPad 2. The processor in the iPad is an ARM processor and Windows (up to and including Windows 7) can only run on x86 processors, such as those from Intel and AMD. (There are other reasons that running Windows would be impossible, but this is the most important reason.)
