This is normal. At the moment of this posting, there
are no "officially supported" FTB-Texture Packs. Meaning, (for now) you have to download them yourself and put them (just like with vanilla minecraft) into your texturepacks folder. That screenshot shows the intended behaviour of the FTB launcher - it's empty.
[EDIT]
In case of "Maps" being empty, too - I agree with EbicNinja: Reinstall the launcher. Because
that one
should have some entries in it.
