winfo class $widget

would help for most standard widgets which have their class hardcoded.
Container widgets such as frame and toplevel allow to specify  arbitrary
class, but it is easy to distinguish between three container classes -
frame, labelframe and toplevel:

if {[winfo toplevel $widget] eq "$widget"} {
puts "$widget is toplevel"
} elseif {![catch {$widget cget -labelanchor}]} {
# widget has -labelanchor option
puts "$widget is labelframe"
} else {
puts "$widget is ordinary frame
}
