If you want an old road frame to convert, ensure it is the right size, has horizontal dropouts and is not a Peugeot (they can be tricky)
Make sure the BB threading, dropout spacing and headtube of the frame are compatible with your langster components and you'll save money. Oh, and get some tools if you don't have any.
EDIT: You'll gain a good deal of knowledge from doing this, but if it sounds like too much hard work, get a respray instead.
