It won't be as simple as that, because there can be multiple transcripts from the same gene. In those cases, which transcript would you consider? Nevertheless, UCSC Table Browser is a good start. It lets you upload/paste a list of IDs and retrieve a variety of information corresponding to those IDs.

In your case, select:

Clade -> Mammal, genome -> Human, version -> hg19, group -> Genes and Gene Predictions, track -> UCSC Genes, table -> knownGene, paste/upload your list of gene names in 'identifiers' section, output format -> Selected fields from primary and secondary tables, give output file name if you want to save the data in a file and click get output.

In the second page, select chrom, txStart, txEnd from hg19.knownGene, and geneSymbol from hg19.kgXref table. I would also recommend selecting kgID from hg19.kgXref (also known as UCSC ID), which are unique for each transcript variant.

Output for your gene names:

#hg19.knownGene.chrom	hg19.knownGene.txStart	hg19.knownGene.txEnd	hg19.kgXref.kgID	hg19.kgXref.geneSymbol
chr1	9711789	9775827	uc001aqa.2	PIK3CD
