There is a 'hardinfo.tcz' extension which has been build as a GTK2 application. Please note that in TC 2.11 the mechanism to create a 'wbar' icon is a wee bit "broken". But you can still start it via the menu or from the command line.
Otherwise I believe I had once (just for fun) build 'lshw' without too much trouble. But it appears I did not keep the result (or the build script) around. You might want to try to build it yourself.
