I tried to install Xcode 4.3.2 from application store, after clicking the Install button, a message displayed as "Installing". (but no progress bar appeared)
After about 30 minutes, (while installation was on progress), my Mac crashed and I had to turn off the power and restart it again.
Now, if I try to install the Xcode again, nothing happens (see the image) after I click the install button except the Apple store login dialog pops in and ask to login.
(No folder named "Developer" has been created in my Application folder yet)

I had the same issue: Xcode couldn't be installed using the App Store. It might be related to having had an earlier version of Xcode installed.
I solved the problem by downloading Xcode from https://developer.apple.com/resources/ . Click on Mac OS X Downloads and enter your credentials (free; not required to be member of OS X developer program), and select Xcode 4.3.2 for Lion from the list.
With this version of Xcode, it was changed from an installer bundle distribution, installing to
/Developerto an actual app, installed to/Applications. Things like developer documentation or command line tools must be installed from Xcode preferences.
